Differentiating Between GIS Electronic Data Conversion and Data Migration

In terms of GIS services, people often get confused by two terms, i.e. GIS electronic data conversion and data migration. Those who know the difference between them are quite relaxed while choosing, but those who have no idea are generally very puzzled during the selection process and with the help of this post, we will be clearing the confusion once and for all.

GIS Electronic Data Conversion vs. Migration: The difference is clear...

Data Migration

The term data migration is used when defining the transferring of data from one system to another. Here is a list of situations in which this term can be used.

• Update PODS model from 3.2 to 6.0
• Switch from UPDM to PODS data model
• Newly acquired pipeline data

GIS Electronic Data Conversion

The term data conversion is used while defining the transformation or translation of data from one format to another.

This data is extracted from a source and then transformed before being loaded in other system or systems.

When this Service comes into the act?

• Legacy data stored in paper files, spreadsheets or CAD files
• Gather information from survey notebooks, as-built alignment sheets, or plant maps
• Convert job books such as hydrotests or FLC reports
• Newly acquired pipeline data

According to those offering GIS data conversion services, the major role in both these processes is of the data technician who will do the following tasks. – 

• Capture, convert and load pipeline data
• Compare converted data with source documents

Then, the GIS Technician also has some work to do in terms of GIS data conversion services and their role would be to analyze spatial and technical data, create databases and then, create and manage feature classes and spatial data.

Conversion Process – 

• Identifying Data Source(S)
• Reviewing Where The Data Is Coming From
• Reviewing What Information Might Be Missing Or Inconsistent
• Identify Data Destination(S)
• Defining The Data Requirements 
• Ensuring  The Needed Data Can Be Properly Translated And Converted 
• Data Load And Review

Migration Process – 

• Database Review
• Review Of The Current Implementation Is Conducted
• Data Mapping
• The Final Migration Process

Understanding the Problems and Solutions Related To GIS Data Conversion

GIS data conversion has remained a challenge for most new companies entering into the sector of GIS. This has got a number of reasons behind it and one is the unfamiliarity with the process or the entire thing. The process of GIS data conversion involves converting the analog data into digital formats to make sure that it can be used by different geographical information systems or GIS. 

Just in case you are unaware, this is important to know that most of the digitally stored GIS maps and images are either vector-based or raster-based. There is a difference between both of them and raster data is organized in columns and rows, whereas the vector data is coordinated on the basis of X and Y-Axis. A very interesting fact is that it is very convenient to convert raster-based images into vector-based images and vice versa. Moreover, you will find some GIS systems having this feature of converting raster to vector and vector to raster. Then, there would be some GIS systems that you will find, relying entirely on the type of data fed to them. 

The needs of GIS Data Conversion

Companies often need GIS data conversion services because they have to share the same data with different companies and this has become really easy with the introduction of networking and sharing feature in GIS systems.

Now, this sharing of data can be done really easily and at the same time, the users will experience a reduction of cost and they can even share other common benefits among organizations.

Some of the Challenges Faced During Conversion Include – 

• Different users of data
• Data used for different applications
• Data is viewed differently by different people
• Use of different hardware/software
• Single value/multiple value attribution in systems
• Incompatible data formats

According to the experts of GIS data conversion services, these problems mainly occur because of factors like non-similarity in the data models, data structures and the data media.

Learn about Photogrammetry and Mapping Solutions

Photogrammetry is the process of using overlapping aerial images to extract precise ground position. The word ‘Photogrammetry’ is a combination of three words which basically means light, drawing, and measurement. It is a technique for acquiring dense 3D geospatial data and information.  If any business is searching for some photogrammetric solutions nearby, one must look for the provider that render photogrammetric solutions to meet the user’s needs with the best quality and at a globally competitive price.

Photogrammetry is the process which is as old as modern photography. The science has continued to develop gradually over time, especially in view of the recent technological advancements.

Photogrammetry is used in:

Today, photogrammetry is used for an extensive variety of purposes in the geographical information system (GIS) field, which includes:

• Creating a digital elevation model (DEM)
• Accurate raster image backdrops for visualizing GIS data

Digital Photogrammetry

There are two types of photogrammetry, Digital Photogrammetry, and Hardcopy Photogrammetry. If the digital image is used for the calculation, then it is termed as Digital Photogrammetry. On the other hand, if a hardcopy image is used then it is hardcopy photogrammetry.

There are also two distinct types of digital photogrammetry, which includes:

• Close-Range Digital Photogrammetry

This particular photogrammetry involves the use of a camera mounted on a tripod stand of vehicle. In this method, high-end digital cameras are used to photograph objects from three or more different locations to develop appropriate lines of sight. 

• Aerial Photogrammetry

This method is done by mounting the camera in an aircraft and subsequently taking photographs of the ground. The camera is mounted in an aircraft and is typically pointed vertically towards the ground. Aerial photographs are taken from the air by a special camera mounted in an aircraft flying over the area with the camera axis vertically.

Mapping Issues 

The recent technological advancements in computer vision and machine learning has made the overall process a bit more complex.  The developers of photogrammetric equipment and software face the challenges in providing the mapping solutions that are advanced, and can meet high customer expectations in terms of user-friendliness. Hence, it is crucial to look for digital photogrammetric mapping solutions service provider that can customize the solutions as per the clients’ needs.

Few Facts On Photogrammetric Solutions

The Photogrammetry is a 3-dimensional coordinate measuring technique. It uses photographs as the fundamental medium for metrology (or measurement). The principle used by Photogrammetry is triangulation or more specifically called Aerial Triangulation. 

By capturing photographs from at least two different locations, the “lines of sight” can be developed from each camera to points on the object. These lines of sight are mathematically intersected to produce the 3-dimensional coordinates of the points of interest.

The term photogrammetry was made use of by the Prussian architect Albrecht Meydenbauer in 1867 for the first time, who fashioned some of the earliest topographic maps and elevation drawings.

Digital Photogrammetric Mapping in topographic mapping is well established. But, in the current times, the technique has been extensively applied in the fields of architecture, industry and many others for the production of accurate 3D data.

What Are The Branches of Photogrammetry?

Metric - It deals with the exact measurements and computations on photographs regarding the size, shape, and position of photographic features. These photographs are taken with the help of a metric camera and are mostly used in the engineering fields.

Interpretive - It deals with the identification of the photographic features on a photograph such as shape, size, shadow, pattern, etc. It helps to add value to the information.

Photogrammetry has always presented a very significant “business proposition”, for several reasons:-

• It is cost-effective - LiDAR equipment is costly and needs specialized expertise to operate properly. Photogrammetry requires only a DSLR camera and software that can be run on a standard computer.
• It is easily available - Photogrammetry equipment can fit in the back of any surveyor’s truck, and you can operate it yourself.
• It is multipurpose - Photogrammetry technology has evolved to the point where it’s a great general-purpose imaging tool. 
• In order to avail such GIS Services, you must get in touch with popular GIS Solutions Company.

About UAV Photogrammetric Solutions and Lidar Mapping Basics

If you are interested in pursuing a UAV photogrammetry business or similar, you must purchase the best quadcopter and sensors you can. There will be several opportunities for owners with quality UAV lidar and photogrammetry equipment.

What Exactly Is UAV Photogrammetry

Photogrammetric Solutions is the science of making measurements from photographs. The result from photogrammetry is typically a map, a drawing or a 3D model of some real-world object or land mass.

3D Maps and Models 

In order to create 3D maps from aerial photogrammetry, the camera is mounted on the drone and is usually pointed vertically towards the ground. For using photogrammetric solutions equipment to create 3D models of monuments or statues, the camera is mounted horizontally on the UAV.

Numerous overlapping photos of the ground or model are taken as the UAV flies along an autonomous programmed flight path called a waypoint. To overlap photos of an object or land by 80 to 90% would be difficult to complete accurately by pilot navigation.  It is important to have a UAV which has waypoint navigation technology.

The Photogrammetric Solutions and Lidar Uses 

Through the use of UAV photogrammetry and lidar mapping, there are many products which can be extracted from the aerial imagery. These products include:-

• DEM / DTM / DSM (surface models)

• 3D Building Models and Contour Maps

• Planimetric features and Volumetric Surveys

GIS Data Conversion As a Technology

Today, our lives are driven by the information we have and how we use it. We definitely need information and information processing tools to lead our daily lives, to run our businesses and to run our society.

With ever evolving technology, we are processing way more data than ever processed, and converting it into information. Access to desired information was never this easy.

The terms “Data Conversion” and “Data Processing” are widely and interchangeably used. However, these two are very different approaches when dealing with data. Companies can make use of distinct data conversion and document strategies. These strategies must ensure that their data is compatible with their systems.

About The GIS Data Conversion Technology:

This technology deals with changes required to move or convert data from one physical environment format to that of another. For example, moving data from one electronic medium or database product onto another form. It might be as simple as the transformation of a text file from one character encoding system to another. For instance, the conversion of office file formats. Also, the conversion of image and audio file formats.

GIS data conversion services are used extensively in mapping services where simple raster images are converted to vector models. It can be utilized in industries like telecom, oil and gas, real estate, etc. for the conversion of hard copy into a digitalized GIS format.

Use of GIS Data conversion as a technology deserves a special standing of it’s own as a separate strategic initiative as part of the whole data management process.

The Accurate or Appropriate Data Conversion should Ensure the following:

• Data is converted into an appropriate format that fits the destination database and is transferred correctly.
• Data works in the new destination database and retain it’s quality.
• Data consistency is maintained at all times through all systems using that particular data.

How Does Data Conversion and Data Migration Differ From Each Other?

What if your data is disorganized? Do you need to convert data, migrate data, or both? If you dive in without a strategy in place, you may run the risk of losing data. Therefore, it is best to get a basic understanding of how to work with data.

 

What is Data Conversion and Migration?

 

Data Conversion

It is essential that all of your data is organized into distinct data fields. Each and every data field has a specific format that can be converted into different forms if necessary.

Often you will need to convert data before it can be migrated to a new location. Conversion can be complex because you need to have a complete as well as proper understanding of the form you are converting from. Also, the form you are converting to. If you don’t, you may run the risk of compromising your data and ruining it’s integrity during the conversion process.

Converting numerical fields namely the customer numbers and zip codes, can be especially tricky. Certain programs treat numerical fields differently than other forms of data. It is possible that it may automatically drop or change numbers that start with a zero. If you don’t know this and go to convert a bunch of numerical data, you could end up with a very huge mess.

You may require special or specific tools to help with the data conversion. For GIS Data Conversion, you may contact a renowned GIS Solutions Provider Company.

Data Migration

Where GIS data conversion deals with migration of information from existing information databases to new ones that often require changes in data formats, data migration is the process of moving and merging entire databases or programs.

Data migration may appear simple at first glance, but it’s actually quite complex. It usually involves what is called data mapping. It is a strategic process that maps data from one database to another by looking at where the data lives currently, and where it will be stored, once it is moved.
