I. preparations: 1. first, convert the obtained longitude and latitude coordinates (generally longitude and latitude) to the degree format. The conversion formula is = left (C3, 3) + mid (C3, find ("°", C3) + 3600)/60 + mid (C3, find ("'", C3) +)/(Note: each parameter depends on the actual situation) 2. regenerate an Excel table. The corresponding X and Y coordinates generate two columns respectively. The coordinate information is arranged in sequence under the first row column (such as X and Y.

For deployment purposes, after arcgis9.2 is installed on win2003, The ArcMap and arccatalog cannot be opened, but the arcreader can be opened. Finally, the license problem is found repeatedly, At last, I copied a new license from my colleague. After reading the license again, the setting was successful. In fact, the selected license does not prompt a problem during the installation process, but it cannot ensure that the software is successfully veri

Some customers often ask how to modify the layers Data Source Path in mxd documents in batches and ask them how to manually modify layers one by one. In fact, the batch data source path modification function has been added in ArcGIS 10.0. This article will briefly introduce it. The following operations are performed in ArcMap. 1. First open the map document and confirm the current path of a layer of data (in this example, the data is stored in GDB

again. The general processing principle is: if the calculation is performed on an existing data field, it should be performed in the editing session; if the new blank field is assigned a value, this can be performed outside the editing session. For element classes that participate in the topology or geometric network in Geodatabase, computing can only be performed within the editing session. For example, you can use the field calculator to copy the value of a field to another field. This funct

First, the preparatory work: 1. Firstly, the obtained latitude and longitude coordinates (generally latitude and longitude) are converted to the degree format, and the conversion formula is =left (c3,3) +mid (C3,find ("°", C3) +1,2)/60+mid (C3,find ("′", C3) +1,4)/3600 (Note: Each parameter depends on the specific circumstances) 2. Regenerate an Excel table, the corresponding x,y coordinates generate two columns, the first behavior column name (such as X,y) in order to arrange the coordinates

Data loss is often seen in the process of using ArcMap software. A red exclamation point appears in front of the layer when data is lost! The data display area has no data displayed. There are two ways to fix this: 1, select the missing data layer, right--properties; 2. Open the Properties window and select "Source", click the Set Data Source button to reset the data source; 3. Open the Window Wizard to browse to the data source to open. 4

Today we're going to talk about a couple of things that don't have much to do with, and if someone has a unique perspective on these issues, or if they already know about the technology, then please put it in the comments for your discussion, so let's explore it. One, these days busy testing and modifying the GIS system, found a number of bugs at the same time also has a new demand, not only changed the interface style and layout and the code also has

Consider the following: [New question] how to load. Net DLL by ArcMap Ask heroes:In vs2008, I wrote a zoomincsharp. CS class and produced a class library. When adding from file to DLL in customsize of ArcMAP, the pop-up dialog box is as follows:Can't load type library from specified file. Do you have similar experiences? How can I solve this problem.In addition, the following warning is displayed

Error message:Use ArcMap to load data in SDE (Data Space reference is unkown). When moving out of the current view window, the following error occurs: one or more layers failed to draw: the specified coordinate exceeds the valid coordinate range. Cause:Domain settings, data is set according to the domain of the Space reference by default when importing SDE. Because the original SHP file space reference is unkown, domain is set according to the data ex

Custom widget of arcgis viewer for flex (pie Chart of arcmap design) and arcgiswidgetCustom widgets can finally implement the first Widget. By convention, we use a Hello World Widget to show how to develop, compile, configure, deploy, and use custom widgets in the Flex Viewer. The source code of Flex Viewer already contains a HelloWorld Widget. Let's try it. 1) install Flash Builder, download the Flex Viewer source code, and use the latest 2.3; 2) Ope

Summary: There is a complete map of China that sometimes requires mapping only for a particular area, so how can I display only the feature content of that range without cropping?Steps:1. Open ArcMap and load the complete map of China;2. The area to be displayed is made into a polygon layer named Cliplyr, and added in;3. Define "Data frame properties"; The range (Extent) consists of three options: Automatic: Default, Fixed scale: Displays only a

Sometimes geometry errors occur when using ARCMAP data processing analysis, and even those errors cannot be analyzed; how can you solve geometric errors quickly? Using the Geometry Repair tool: 1. Open ArcMap to add the data to be repaired; 2, open the Geometry Repair tool in toolboxes, expand Toolboxes--system toolboxes--data Management tool--features (Features)--Geometry repair (Repair Geometry); 3

1. During cropping, make sure that the data of the layers to be cropped has a public part. Sometimes, the data In ArcMap shows a public part. But in fact, due to coordinate system, they are not in the same way. If there are no public parts between several layers, an error will be reported. Check them. Possible error: Error 000953: Extent of the overlay operation will be empty. Solution: Change the coordinates or projection of the layers to ensure that

#1: Use the arctoolbox \ data management tools \ generalization \ dissolve Tool#2: Options: Select "merge fields" for the dissolve field item [merge fields based on those fields, that is, the last reserved fields ]. If you want to include other fields to the result, you can select in statistics field and set the rule [The rules that can be set are limited, that is, the sum, average, maximum, minimum, and so on ].#3: Special tips: The create multipart features option is shown below. If this optio

In the process of making a thematic map, not only should there be geographical elements to represent the spatial location, but often also to make some tabular data around the graph. Here is a summary of the insertion method in ArcMap.Method One: Insert an ObjectUse Insert-object in the menu to add almost any type of data to the map. Official Help NotesYou can also edit the data by using the application that the data belongs to.Method Two: The property sheet is added to the layoutWhen you create

One, add data connection1. How to connect a folder2. Database connection mode, note: Publishing a map feature service, you must use a database connection.Second, view the map1. Drag and drop the selected map file or database file directly into the ArcMap template window to display the map, and if the map is not displayed, right-click the layer in the Argmap left window and click Zoom to layer.Iii. Publishing Services (feature access is selected for pu

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
