GIS data capture

What is a GIS

A geographic information system (GIS) is a framework for gathering, managing, and analyzing data. Rooted in the science of geography, GIS integrates many types of data. It analyzes spatial location and organizes layers of information into visualizations using maps and 3D scenes. ​With this unique capability, GIS reveals deeper insights into data, such as patterns, relationships, and situations—helping users make smarter decisions.

We provide

Sylloge provides GIS ready data files to your requirements

For ArcGIS organisations  we provide data to your table schema.

We can also setup your GIS from scratch using the well regarded open source QGIS software . QGIS will provide most of ArcGIS features for no licensing cost.

 

 

Data Capture

 

We capture information in two ways, Aerial  photogrammetry and/or GPS point data collection

Using the image above as an example of the data we can provide:

A precise GPS survey is carried out, this is the (MGA56 control) layer, this can be expanded to any point location information that is required.

A Drone survey is flown and imagery is captured, this is in two parts.

Oblique imagery is used to create orthomosaics (2.5cmOrtho), terrain models (2.5cmDTM), through to engineering plans (1m Contours). Line and polygon features can also be extracted from the Orthomosaic.

Perspective imagery (perspective photos) can be captured and image location shown on the GIS with a link to open the photo.

Background layers can be added with any GIS’s, here (Bing satellite) is used, there are many options.
