GIS and Geospatial Technologies

Articles focusing on the application of geographic information systems (GIS), geospatial technologies, remote sensing, LiDAR, and Global Positioning System (GPS). These technologies serve as critical tools for understanding and interacting with our physical environment. GIS allows for the mapping and analysis of spatial data Geospatial technologies refer to the various tools used to measure and analyze Earth’s lands and resources. Remote sensing provides a way to collect data from a distance, often via satellites or high-flying aircraft, and is commonly used for environmental monitoring and military applications.

The 2015 earthquakes caused great damage in Bhakatpur, Nepal. These photos are overlaid on a damage proxy map derived from COSMO-SkyMed satellite data. Colors show increasingly significant change in terrain/building properties (including surface roughness and soil moisture). Red is most severe.

Shapefiles store vector information such as points (represented by well locations in this map), lines (river), and polygons (lake).

What is a Shapefile?

Caitlin Dempsey

The shapefile format is now a common format for storing GIS data. Shapefiles store non-topological vector data along with related attribute data.

Line of Sight: Track the Real Time Locations of Satellites

Elizabeth Borneman

Line of Sight is an online map application that tracks where each and every satellite is above the Earth in real time.

VDGIF worked with Timmons Group to update a legacy web application created several years ago titled “Find Game”. The project was managed as an agile design process. Our team used agile techniques to help in the design process presenting various “iterations” of wireframes for the VDGIF product owner to review. This enabled us to focus on high-priority needs and put lower priorities into the backlog.
