last one is to reset the center point of JS, although the map will automatically set a new center point, but we also do a perimeter search, we must first match the most qualified results as the center of the region search, so this here first to make it out. If you want to display the search results as a list, simply modify the creation of the Srender object:Srender=new sogou.maps.SearchRenderer ({' Panel ':d ocument.getelementbyid (' result ')});This result is the ID of the previous div on

One of the most frequently mentioned concepts in GIS (Geographic Information system Geographic Information System) is the coordinate system, which, when we mention a geographic location, is accompanied by a spatial reference. When we use a GPS device to get latitude and longitude in a location, we actually get a spatial geographic coordinate under a WGS-84 ellipsoid coordinate system. At present, the space coordinate system is very numerous, these coo

In the "HT for Web integration openlayers implementation of GIS Map Application" chapter introduces the integration of HT for Web and Openlayers, many friends respond to the domestic use of more than Baidu map, although the integration of the principle of the integrated Baidu map with openlayers consistent, But different GIS engine client combined with code details or a lot of differences, custom map style

. This provides a possibility for the implementation of GIS. According to the actual work needs, the author uses SVG and related technology in Web browser to realize the Web GIS Management System (hereinafter referred to as Webgis), and obtains the very good result. This system includes the design of the server and the client, which is to handle the data storage and the dynamic loading of the data, the clie

How to copy a GIS image to the Windows clipboard and paste it to the word I haven't written this article for a long time. I want to shut down this blog and stop updating it, but I still have no determination. Let's take a look at these days. Let's send a function that was previously written to play.The copy and paste functions are simple, but how can we paste GIS images into word? The simplest idea is to sa

Grid Data uses a regular grid to describe the location and value of spatial symptom features corresponding to the location of each grid unit. In terms of concept, changes in spatial phenomena are reflected by changes in grid unit values. Many data in the geographic information system are expressed in a grid format. Grid Data is complementary to vector data in many aspects. Combining the two types of data is a common feature of GIS projects. I. Element

ESRI shapefile(SHP) is an open space data format developed by ESRI. Currently, this file format has become an open standard in the geographic information software field, indicating the importance of ESRI in the global geographic information system market. I read some documents and was interested in one sentence. "The shapefile file does not contain the topological data structure" [Several other problems arising therefrom] What is topology? What file formats contain topology data structu

compression, it has the same performance as the shape file and is stronger than personal geodatabase. When the same data is stored, File geodatabase reduces the disk footprint by 50% to 80% compared to the personal geodatabase.ArcGIS provides tools to extract a file geodatabase from the geodatabase in the DBMS form and to put a file geodatabase in the human DBMS. Users can easily create file Geodatabaee by loading data from any other geodatabase or supported file structure, such as a shape file
