Inspired by John Nelson’s work in the Cartography team at ESRI I wanted to create a paper cut out effect for the bathymetry of the Mediterranean and the Black Sea using ArcGIS Pro 2.2. The effects developed by the ESRI Cartography...

Read moreIn a previous blog I mentioned how ArcGIS Pro did not have the functionality to create geodesic lines. Well there is an add-in available for that now and it can be used in ArcGIS Pro 1.4 – 2.0 as well...
Read moreGeomatics World has published, in their September/October 2018 issue, an article, written by Simon Kettle, on how the European datum of 1950 came about and how it became the de facto standard after World War II. Read the article in Geomatics World Read more…
I own this map and perhaps one of the interesting things about this map is not only the wealth of information available and aesthetic quality but how over 40 European and adjacent countries worked together to create the seamless geology map Read more…
What are Geodesic distances? A geodesic line is the shortest path between two points on a curved surface, like the Earth. They are the analogue of a straight line on a plane surface or whose sectioning plane at all points along the line remains Read more…
Introduction Map scale is one of the most important factors to consider when representing data on a map. It is important not to lose the message of the map by including too much data. The standard way of controlling the Read more…
What is a Vertical Datum? The Geodetic Glossary (2009) defines height as ‘distance, measured along a perpendicular, between a point and a reference surface’. This definition is concise and direct but leaves a vagueness concerning the reference surface. This reference surface is the Vertical Read more…
I decided to look into some of the mathematics that makes it possible to calculate distances considering 3D space, for example, calculating distance on a sphere. The Earth is round but big so we can consider it flat for short Read more…
We thought to kick off the Geospatial Geoscience blog with an awesome tip concerning ArcPro. After initializing and getting data into the software it quickly became apparent that the usual long list of styles was no longer there! Symbology groups Read more…
