MGET is a set of tools that provides us the capability to download chlorophyll data. This kind of data is really important for modeling and visualizing raster layers according to the presence of chlorophyll on the map. To start with, we are going to search for NASA GSFC Ocean Color. This website hosts a great deal [...]
In this demonstration we are going to show the steps for calculating a Relative Relief from a Raster in “.asc” format, DTM. […]
To improve the quality of our map, it is important to know that it is possible to customise the symbology, this means, to get the features adapted to what we want to represent on the map. […]
One of the most common analysis used in every GIS is to represent service areas around any location, using, at first, a Buffer Analysis. In this example, we have used a ArcGIS Desktop application: ArcMap. […]
The ArcGIS Course applied to Geology and Mining is particularly suitable for professionals in these areas who want to gain an advanced knowledge of this powerful software, and specifically of those tools that are very useful to the fields of geology and mining. Let’s review in this post some of the most interesting contents regarding [...]
The United States Geological Survey, USGS, is an organization of the United States government that provides reliable information regarding the status, threats and condition of the Earth, being the largest mapping agency in the country. It shares information from all around the world. […]
