Agentic AI Experience Starting with MCP for ArcGIS Location Services
はじめに 近年、AI は単に質問へ回答するだけでなく、外部サービスやデータを利用してタスクを実行する「エージェンティック AI」へと進化しています。こうした AI が外部システムと連携する仕組みとして注目されているのが Model Context Protocol (以下、MCP) です。 ArcGIS 開発者コミュニティでもこれまでたびたび取り上げてまいりましたが、地理空間分野でも MCP の活用が広がっており、行政オープンデータや衛星データ、さらには ArcGIS の位置情報サービスを自然言語から利用できるようになっています。本記事では、地理空間業界における MCP と、米国Esri が提供する MCP for ArcGIS…

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?

Enable the FeatureLayer.calculate() method in the ArcGIS API for Python to accept Arcade expressions for calculating attribute values.

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…

RTK Streams with Reference Frame ITRF 2014 Unable to handle On-the-Fly Projection/Transformation in Field Maps
I've been using and helping others configure and utilize RTK corrections from various services in Idaho, Oregon, and Florida. A couple of the major RTK service providers have switched from NAD83(2011) to ITRF 2014 with a specific Epoch as their reference frame. This is a time-dependent reference frame that accounts for the…
