Google Maps for Android is one of the most actively developed Google apps, with new features and improvements routinely being added to the navigation app. In the last two months alone, the app has gained quite a few functionalities, including a new community feed, a Go tab for accessing frequently visited places, messaging for verified businesses, a new driving mode, and food delivery alerts. The app will also soon start showing COVID-19 vaccine locations in the US. Now the Google Maps on Androi

You’d be forgiven for thinking that receiving data transmissions from orbiting satellites requires a complex array of hardware and software, because for a long time it did. These days we have the benefit of cheap software defined radios (SDRs) that let our computers easily tune into arbitrary frequencies. But what about the software side of things? As [Dmitrii Eliuseev] shows, decoding the data satellites are beaming down to Earth is probably a lot easier than you might think. Well, at leas

Hi readers, I have a dataset of ~60,000,000 rows of lidar point data. All spatial reference points are projected using ESRI:102673 (full WKT here: https://epsg.io/102673). I need to convert this to latitude and longitude, EPSG:4326, so that I can overlay other layers and have them match up in the same spacial reference. I am using Python, so any transformation I can do using numpy or pandas will work, or any other free software that gets the job done would be great. This tool (https://

Hi, I have two layers of polygons (gaps in the city) with unique IDs and smaller "lots". These gaps are dissolved from these smaller "lots" polygons (in some cases one lot is equal to one gap). These smaller polygons have the same ID (all ID1 lots - creates one ID1 gap). I have three types of these smaller lots polygons, let's say a, b, c. How to calculate the percentage share (or spatial share ha) of these individual (a,b,c) types of lots in the gap ? Ex: ID1 gap: 30% - type a 50% - type b 20

Basically, I want to add a feature point by a coordinate in QGIS where the feature itself is loaded from Postgres database. I know there is a plugin called LatLon Tools which provides the tool but sadly it cannot be done when the layer is loaded from Postgres database. anyone knows how to do it?
