Article directory The message passing mechanism of the entire process: 1.OnMapReplaced implementation 2.OnMouseDown implementation 3.OnExtentUpdated implementation Two AxMapControl controls are required to implement the function of the Eagle Eye Chart. We will use axMapControl1 as the main view and axMapControl2 as the Eagle Eye Chart. The placement in the form can be customized. I use […]

ArcGIS API for Javascript calculates length, area, distance and buffer in different coordinate systems
ArcGIS API for Javascript has a variety of methods for calculating length, area, etc., which we often get confused. Today we will briefly review the applicable scenarios of each method. 1. Calculate the length import * as geometryEngine from ‘@arcgis/core/geometry/geometryEngine’ import * as geodesicUtils from ‘@arcgis/core/geometry/support/geodesicUtils’ /** Calculate length * @param {Geometry} geometry geometry * […]
Modeled through kernel density analysis tools, loading gp service based on arcgis js api 4.27
1. Modeling through arcmap10.2, which contains three parameters Pay attention to the input attribute and select the data type as feature class: 2. After modeling, load the data and execute the model. If there are no errors, find the execution results and publish the gp service. Note that when publishing the gp service, the parameters […]

Dry information I DBSCAN clustering algorithm is implemented in Python and applied in ArcGIS Pro
** Algorithmic Thoughts Sharing of useful information ** DBSCAN (Density-Based Spatial Clustering of Applications with Noise, density-based clustering method with noise) is a typical density-based spatial clustering algorithm. Compared with K-Means and BIRCH, which are generally only suitable for clustering of convex sample sets, DBSCAN can be applied to both convex and non-convex sample sets. […]
ArcGIS construction ideas in the VUE framework
The project is about to go online, and I unexpectedly have some free time. I thought about optimizing the map-related code in the first phase of code developed by other companies. During the trial run, customers said that there were a lot of red errors in the console. They were very concerned about it. Although […]
