Chrome Developer Tools Invoke Property Getter

由 元气小坏坏 提交于 2019-12-04 16:43:18
问题 All of my property values require me to click them in order to see them. How can I fix this? The object I'm trying to view is this Query Object. It seems to do this with most Arcgis objects I'm trying to view. 回答1: The issue is, calling a getter can have side effects e.g. class Dog { get paws() { console.log('paws!'); //side effect this.paws++; // side effect if(this.paws > 4) { throw Error('oh no'); // side effect } return this.paws; } } Every getter can alter the state of the app or break

How to pick up the information for the nearest associated polygon to points using R?

问题 I'm figuring out how to do a Intersection (Spatial Join) between point and polygons from shapefiles. My idea is to get the closest points and those points that match completely inside the polygons. In ARGIS there's a function for match option named CLOSEST and they have defined by: "The feature in the join features that is closest to a target feature is matched. It is possible that two or more join features are the same distance away from the target feature. When this situation occurs, one of

How can I use Esri Arcgis Map in ReactJs Project?

由 ￣綄美尐妖づ 提交于 2019-12-04 11:44:17
问题 I'm trying to use Esri map. To include map in my project, here is what I found: require([ "esri/map", "esri/dijit/Search", "esri/dijit/LocateButton", "esri/geometry/Point", "esri/symbols/SimpleFillSymbol", "esri/symbols/SimpleMarkerSymbol", "esri/symbols/SimpleLineSymbol", But there isn't any esri folder or npm package. Therefore, I'm confused here. How esri is imported in project? 回答1: An alternative method to the above is the one demonstrated in esri-react-router-example. That application

Help plotting Geographic Data in R using PBSMapping and Shapefiles

由 让人想犯罪 __ 提交于 2019-12-04 05:42:10
Using O'Reilly's Data Mashups in R as inspiration, I'm trying to plot a handful of addresses on a shapefile of Salt Lake County, Utah found here . I have data frame geoTable: > geoTable address Y X EID 1 130 E 300 S 40.76271 -111.8872 1 2 875 E 900 S 40.74992 -111.8660 2 3 2200 S 700 E 40.72298 -111.8714 3 4 702 E 100 S 40.76705 -111.8707 4 5 177 East 200 S 40.76518 -111.8859 5 6 702 3rd ave 40.77264 -111.8683 6 7 2175 S 900 E 40.72372 -111.8652 7 8 803 E 2100 S 40.72556 -111.8680 8 And I've coerced it into an eventData object: > addressEvents<-as.EventData(geoTable,projection=NA) >

Adding custom Feature attributes to ESRI Shapefile with Python

由 这一生的挚爱 提交于 2019-12-03 14:48:53
I am seeking a way to take an existing ESRI Shapefile that has a Feature set of 200 countries. Each country Feature has an attribute of "NAME." My objective is to create a Python script that adds an arbitrary (for now) additional attribute, say, "POPULATION". Of course I have the OSGeo and GeoDjango modules installed. I'm as far as: from osgeo import ogr infile = ogr.Open('sample.shp', 1) #'sample.shp' is a pre-existing ESRI shapefile described above inlyr = infile.GetLayerByIndex(0) Am I missing an OGR function that will allow me to insert Feature attribute fields into an existing Shapefile?

移动GIS开发之加载Esri地图

由 不想你离开。 提交于 2019-12-03 11:06:35
选择AndroidStudio进行简单的移动GIS开发，添加一个Esri的公共地图。 目录 1、新建项目 2、选择Android系统版本 3、添加空白例子 4、输入Activity Name 5、配置Esri的在线SDK 6、添加网络权限 7、将MapView添加到布局中 8、在MapView里设置地图 9、点击运行开始 1、新建项目 输入项目名称和公司名称。 2、选择Android系统版本 选择较低版本的可以获得更高的兼容性。 3、添加空白例子 4、输入Activity Name 5、配置Esri的在线SDK Gradle Scripts中在项目级的build.gradle文件里，在repositories块中，将Esri的maven存储库URL添加到项目中。 Esri的存储库不是开源的，因此在脚本的默认存储库中不可用，因此您必须指定此URL。 allprojects { repositories { google() jcenter() // Add the Esri public Bintray Maven repository maven { url 'https://esri.bintray.com/arcgis' } } } 在模块级build.gradle文件的依赖项块中，将ArcGIS Runtime SDK for Android依赖项添加到您的应用程序。

AE开发常见问题总结

由 ☆樱花仙子☆ 提交于 2019-12-03 10:21:12
一、 Arcgis10.0 组件初始化失败 解决方法： ESRI.ArcGIS.RuntimeManager.BindLicense(ESRI.ArcGIS.ProductCode.EngineOrDesktop);该语句需要引用ESRI.ArcGIS.Version类库 二、无嵌入互操作类 解决方法： 嵌入互操作类改为false,在VS2010中，使用.NETFramework 4.0环境时，ESRI的类库嵌入式互操作属性需要设置为False。 三、向axMapControl控件中添加shp时，出现了“The specified path is invalid”这个错误，仔细检查代码并无错误;而从文件添加Layer则可以，但ToolBarControl无显示。 解决方法：添加axLicenseControl 控件 四、清除数据集没反应 解决方法：清除数据集前必须先刷新 activeView.PartialRefresh(esriViewDrawPhase.esriViewGeoSelection,mapControl.get_Layer(0),null); mapControl.Map.ClearSelection(); 　　　　　　 activeView.PartialRefresh(esriViewDrawPhase.esriViewGeoSelection,
