Student Maps on the Move: Real-Time Feeds and Analytics with ArcGIS Velocity

Translations in Experience Builder
V ArcGIS Experience builderu na AGOL přibyla možnost překladů. Narazila jsem ale na to, že defaultní jazyk je automaticky nastaven na jazyk profilu, který aplikaci vytváří, ve chvíli, kdy aplikace vznikla. A toto nastavení následně nejde změnit. V naší organizaci má většina lidí, která vytváří aplikace, má nastaven profil…

Count Points in Polygons using the ArcGIS API for Python
Spatial analysis often involves answering a deceptively simple question: How many features are located within each area? How many properties are in each district? How many trees are in each park? How many incidents occurred in each administrative boundary? How many inspection points fall within each service area? This post…

Enable the FeatureLayer.calculate() method in the ArcGIS API for Python to accept Arcade expressions for calculating attribute values.
Current limitation The FeatureLayer.calculate() method currently supports calculating field values using SQL expressions or scalar values. However, there is no direct way to apply an Arcade expression through this method. This creates a gap for workflows that rely on Arcade for attribute calculation logic, particularly…

Let add-ins read a raster layer's joined attribute table (IDisplayTable for raster layers)
Summary of the problem ArcGIS Pro lets a user join a standalone table to a raster layer's attribute table (Add Join on any raster with a VAT). The joined columns then behave like part of the raster's attribute table everywhere in the application: they appear in the attribute table view, in pop-ups, and in the Symbology…
