How to Find Out Whether a Location is on Land or Water

By Richard Süselbeck | 27 October 2020

I was recently working on a different project and thought it might be useful to know whether a given location (latitude and longitude) is either on land or in water. Finding out how to do this was a little bit tricky, so I thought I’d share how to do this in a blog post. What we’ll be building is a simple web app, which allows you to click on a map. When you do this, an info bubble will pop up to tell you whether you clicked on land or water! If you’re in water, the info bubble will also tell you what the name of the body of water is.

Create a WKT File Using HERE Data Layers and Geopandas

By Shruti Kuber | 26 October 2020

A few weeks ago, I was working on a demo where I drew geofences around brick and mortar stores. When my user is near this geofence, they get a notification about the offers in the store. Sounds cool doesn't it? Step 1 of this demo is to create a geofence in the WKT format. Normally a geofence is created by manually drawing polygons around a place and extracting them as WKTs. I was looking for a better method to automate this. This is when I came across Geopandas. Geopandas is a Python library that works specifically with geospatial data. Couple this with the Buildings HERE Data Layer and you can get geofences for different buildings in a city within minutes.
