ARCserver Development Summary (III)

1. Create a network Dataset

Because the network analysis function is to be implemented, but there is no network dataset in the hands, there is a lot of information on the Internet for the production of network datasets. For more information, see esri's help document (network_analyst_tutorial.pdf. This document is located in c: \ Program Files \ ArcGIS \ documentation. Of course, this path varies with the ArcGIS installation path, I think the most important thing is that when you step by step next, it is generated. after the nd file (Network dataset) is completed, open these files In ArcMap and use the network analyst provided by ArcMap) generate a new route, service area, closest facility, or OD cost matrix. Which one to generate depends on your system needs, for example, the shortest path, it is necessary to generate a new route. Well, save the mxd file. At this time, you can publish this document as mapping and net analysis.

II. A little detail about ext

My extjs version is 2.21.

Sorry, this is a blank image. This is not a problem. If my webpage is not connected to the Internet, this image will definitely not be available.

You can search for the extjs source file and find Ext. the resource that is connected to the character "blank_image_url" is the resource on the ext official website. In order for the system to download images from the local machine, rather than go to the ext official website, therefore, add the following sentence at the top of the called JS page.

Ext. blank_image_url = './scripts/EXT/resources/images/default/s.gif ';

That is, specify an image for this character.

The webpage will not be downloaded from the official website, but from the local machine.
