This Wpf project completes the series of projects dedicated to the clipping geoprocessing. We already saw how to perform clipping on a polygon based layer in “Clipping” and on a point layer in “Clipping On Point Layer”. Here we show how to perform the clipping geopressing on a line based layer. As for the same operation on a polygon based layer, the key geometric function is GetIntersection. We will also appreciate the operation of creating a layer from scratch as in addition to the geometric operation itself, geoprocessing also involves creating a result layer from the original layers, the clipping layer and the clipped layer. You will need to get in the Dev Daily Build the latest MapSuiteCore.dll and WpfDesktopEdition.dll as references as the GetIntersection API for line based shapes was added only recentely.
In today’s Desktop project, we learn how to create inner rings to a polygon based on another polygon using the GetDifference function. We also learn how to perform Union on a collection of polygon and how to set up the event TrackEnded. To use this app, you need to track a polygon, double click to end it and it will create an inner ring from the unioned result of the polygons completely within the tracked polygon. You can look at the TrackEnded event handler to see all the different operations taking place for that task.
In this sample, we learned how to use the method GetFeaturesWithDistanceOf when the data is projected. We just input the unit which is projected to, do not need to mind what the real unit is for the internal data before projection. It works fine with Map Suite Assemblies 4.5.54.0 or later.
The purpose of this project is to show how to use the FeatureIdsToExclude collection of FeatureLayer. In the project, you will see how you can exclude some features from being part of the GetFeaturesNearestTo function. Using that collection is a handy method for not taking into account some features in doing spatial queries, searching and even drawing without having to change the structure of the layer or create another layer.
This project is basically the Web version of the previous project “Get Feature Clicked On”. You can see in the Map_Click event of the map the logic for selecting the closest feature clicked on within a buffer in screen coordinate.
This project is a more advanced version of “Get Feature Clicked On (Web)”. We show how to deal with the scenario where you want to get the nearest feature clicked on using multiple layers of different types (point, line and polygon). To have smooth behavior on that function, you need to give priority to point based features, and then line based features over polygon. Please, look at the code to see how this is accomplished.
In today’s project, we show how to split a line based on an intersecting line. To accomplish this task, basically two steps are needed. First, you need to find the crossing point using the GetCrossing function and then you split the line based on the crossing point using the GetLineOnLine function. If you are in the utilities industry working with electric network, gas pipes etc, you will find this project useful.
In this Wpf project, we show how to create a MultipolygonShape from various PolygonShapes. Since a collection of PolygonShapes cannot be directly cast to a MultipolygonShape, we show the technique to build a MultipolygonShape passing an IEnumerable of PolygonShape. This is a Wpf sample and you will need the references for MapSuiteCore.dll and WpfDesktopEdition.dll.
version 7.0.318.0 or later.
The purpose of today’s project is to show how to make a desktop project from a Servicess one. Many of the projects published in the Code Community are in the Servicess edition because the only reference for Map Suite required for running them is MapSuiteCore.dll. That dll comes in any of the Map Suite products. We are taking the example of the “Sweep Angle” Servicess project to show how to adapt it to a Desktop project. With the understanding of some basic concepts such as Overlay, you will be able to easily convert a Servicess project to a Desktop one. So, for this project, you will need the references for both MapSuiteCore.dll and DesktopEdition.dll. Next, we will see how to convert a Servicess project to a Web one.
