This is a very interesting question.Now I'm a point layer called "Wenchuan 73", there is a polygon layer also called "Wenchuan 73", using the spatial connection tool to calculate how many points each polygon is falling into. However, no matter how to calculate, the result can only generate points, can not generate polygons, this tool is the case, see the Help or do not understand.I make a connection in the property sheet of the polygon (by Space position), then can be born in the face file, whic

The first method: Extract values to points tool, this online more information. Don't introduce it. It's because my computer can't execute the tool, it's always wrong, but I don't know what the reason is. To realize this function, we have to find other ways. Later through the teacher's guidance, found that 3D analysis inside some tools are very useful, deliberately recorded down.Second method: Interpolate shape ToolExecuting this tool will ask you to enter a raster surface, view the attribute tab

no part is within the source feature. In this case, the target feature will not be selected using the "Within the other features (Clementini)" operator, and the target feature will be selected using the "within the other features" operator. The Clementini operation specifies that the boundary of the polygon is independent of the interior and exterior of the polygon.Clementini involves the "within other features" and "include" topological relationships defined in the following articles: Eliseo C

In the case of a map registration, sometimes a map that needs to be fitted is not the direction you want, so you may need to rotate the photo to the left or right at this time.After the picture viewer is rotated and saved, it is very simple to have a time finding in arcmap that still does not save its rotated image. The steps are as follows:1 load the image to be fitted and load the Georeferencing toolbar.2 Locate the georeferencing > flip or rotate i

You can often see questions about how to calculate the area and length In ArcMap. In the past, I had a blog post about this. Article It is very clear that it is implemented using VBA. Here we describe the calculation process again. The SHP file of the prefecture-level cities in Guangdong province is used to calculate the area of each prefecture-level city and the length of Multi-deformation, paste the image in the step at the same time. 1. load data

Many users in the process of using ArcMap software, the phenomenon of data loss often occurs. A red exclamation point appears in front of the layer when data is lost! The data display area will have no data displayed. So how to get the lost data back? Small knitting to teach you to solve. 1, select the missing data layer, right key--Properties 2, open the Properties window select Source, click the Set Data Source button to reset the data

Recently, due to the needs of the project, you need to register the content in the planning map to a map with a standard geographic coordinate system (WGS84). After many attempts, after many detours, finally, we found a feasible method.Write it here

If you set the coordinate system when creating a new feature class or dataset, we use the coordinate system's (Map Projection) Valid extent. this is larger than the coordinate system's valid area of use. for example, in your case, the extent of

Some time ago, I tested the process of calling gdal/OGR to read and write the shape file with C #. The overall process looks simple. Today I will summarize it a little bit: 1. The OGR class library reference has been comprehensive on the official

Copy the map document and open it again! Because the relative path of the loaded layer changes, you need to re-specify the layer position. In this regard, the. mxd document is set to a relative path, the specific method is as follows:(1) file -->

In practical applications, you will often encounter a high-precision map image file, how to register the image (so that the image has latitude and longitude coordinates ). Of course, we have to have some rough reference layers. Registration

When labeling a layer, there are often some annotations that do not appear after the conflict, and some individual point features need to be adjusted for labeling, such as:The process steps are as follows(1) Open the Maplex label engine. Open the

The first method: Extract values to points tool, this online more information, it is not introduced.The second method: the Interpolate shape tool is directly used with the arc toolbox->3d Analyst tools-> Functional surface->interpolate shape tool.
