GIS maps are very detailed and can contain a lot of complex data. Learn more about raster vs vector for GIS maps so you can print with the right file types.

MapLibre GL is a community-led fork derived from mapbox-gl-js before their switch to a non opensource license. One of the fancy possibilities of mapbox-gl-js is to display the terrain. This functio…

The OGC API — Common Standard is a multi-part Standard that specifies reusable building-blocks that can be used in the construction of OGC API Standards. The OGC API — Common — Users Guide presents information useful to developers or users of implementations of the OGC API — Common Standard. The information in the Users Guide is not normative. That is, it is not mandatory. However, it may prove essential to fully understand the normative text in the OGC API — Common Standard. The Users Guide is therefore intended to serve as an aid to developers and users.

The National Zoning Atlas https://www.zoningatlas.org/ is a collaborative project digitizing, demystifying, & democratizing ~30,000 U.S. zoning codes.

In this tutorial I will show how to set up PostgreSQL with PostGIS to run spatial queries in R. I cover installation of PostgresSQL, creating schemas, saving data to tables, connecting from R, and running spatial queries.

The National Flood Hazard Layer (NFHL) is a geospatial database that contains current effective flood hazard data. FEMA provides the flood hazard data to support the National Flood Insurance Program. You can use the information to better understand your level of flood risk and type of flooding.

What are GIS Standards? Why do we need Geospatial Standards? Which common GIS Standards are existing for spatial data formats, metadata and services? Who are the standard oranizations? How do they work?

The hundreds of checkboxes and data fields that make up a home appraisal report determine the fate of your home sale. Let’s review each section!

Before you can design and build, your construction project needs a thorough architectural site analysis. Learn the steps and what to record.

I always edit the images in JOSM first and then upload them. But that’s always more difficult because they hide the gps data somewhere. So my question is whether anyone knows of an alternative for taking pictures with a smartphone. Of course, it would also be good if it were not only time-controlled but also speed-dependent.

Site analysis for real estate development is one the basic prerequisite for the feasibility study and development analysis. Read more.
