GDIC provides utility GPS mapping services and data collection services for Municipal planning and underground utility facilities i.e. gas (high and low pressure), electric, telephone, television cable, sewer, water and deep-water services within city limits (urban locates) and beyond (rural locates). GDIC Provides GPS mapping services of variable
accuracy up to 1cm.
Data Collection
What is Geospatial Data Collection?
The process of geospatial data collection has becomes more and more demanding and remains one of the most expensive data-based activities for GIS integration. Data collection mostly deals with sources and information with specific parameters that is gathered so that it can be integrated into GIS. GIS is a very useful tool, it can be utilized for almost every type of infrastructure related project, helping users plan and make smart decisions effortlessly.
Categories of Data Collection
Data Collection can be split into the categories data capture (direct data input) and data transfer (input of data from other systems). There are two main types of data capture and they are
- Primary data sources are those collected in digital format specifically for use in a GIS project.
- Secondary sources are digital and analog datasets that were originally captured for another purpose and need to be converted into a suitable digital format for use in a GIS project.
Cost of Data Collection
Data collection is a time consuming, tedious, and expensive process. Typically it accounts for 15–50% of the total cost of a GIS project. If staff costs are excluded from a GIS budget, then in cash expenditure terms data collection can be as much as 60–85% of costs.
GDIC alleviates these prices by providing extremely cost effective collection services for clients. With our 360˚ model, our services come at a fraction of the price of other companies.
GDIC Geospatial Data Collection Services
Many municipalities and infrastructure related projects require either original or supplemental field data collection. This process is extremely time consuming, difficult to coordinate and expensive. To make matters worse, once this data is collected it is not integrated in GIS, making the data limited in its helpfulness and capacity.
GDIC can manage data collection projects deploying data technicians to the field with handheld tools driving an integrated and efficient data collection process. This can include the use of both consumer-grade technology and extremely precise industrial-grade GPS mapping systems. Additionally, GDIC can deploy integrated devices with form-based workflow for superior data quality control. Once this geospatial data is collected, GDIC can integrate it into Web-GIS while also converting it into different file types to increase its compatibility. GDIC has a team of GIS and field professionals who can deliver complete project services, from the field to the desktop.
GDIC’s Collection Process
Establishing user requirements, garnering resources, and developing a project plan.
Obtaining data, redrafting poor-quality map sources, editing scanned map images, removing noise, setting up appropriate GIS hardware and software systems to accept data.
Stages where data will be transferred into a digital format. This is where the majority of the effort will be expended.
Techniques designed to validate data, as well as correct errors and improve quality.
Identifying project successes and maintaining what was achieved for the client.
