The MapGuide GIS system asked for help. An error was reported when connecting the SDF file with FDO. The solution was not found in a few days. mapguidesdf Currently, there is very little information about the GIS system on the Internet. However, most people use WebGIS. Here, MapGuide is used for GIS presentation and MapWindow is used for layers in the background,

GIS (4) -- add borders + the final simplified version of Marker and Brand for the js sogou map, gismarker In GIS (III)-brand logo style for optimizing sogou map of js edition, I shared my changes to Brand style. Now, let's unify the changes made to the Marker and Brand, and then make them a final optimized version. The main content of this optimization is: 1. Create a boundary first. Adding a boundary to a

1 , overviewThe urban construction process is speeding up, the urban planning management is becoming more and more heavy, the data of various sources produce various problems, which seriously affect the accuracy of urban planning, so we can make more scientific decision by mastering all aspects of urban planning information comprehensively and rationally. The rise of mobile has provided great convenience to the dynamic aspects of planning, all kinds of the deep development of wireless terminal,

Due to work reasons, I have been studying the controls of GIS over the past few days. I mainly read the controls of Supermap and MapInfo. The main achievements are as follows: 1. Most GIS controls have these controls: mapcontrol is used to display maps, zoomin, zoomout, roaming (used to drag a map), moving left, and moving right. 2. I watched some flash and some examples and found that the main functions

1. PrefaceThis week, I did some preliminary exploration of open source software and related technologies and processes involved in the open source solution for GIS, as well as some of the more mature cases that other companies have done with open source solutions. Here I will some technical key points of the preliminary research to do a summary, while the other companies open source success stories to do an analysis, and put forward the personal think

The GIS business development stage is divided: Phase 1: digitalization. At this stage, people are new to GIS. The main business is to digitize previous data;Stage 2: visualization. The user uses spatial data for two-dimensional drawing and three-dimensional roamingCodeConvert to images that are easier to accept and perceive;Stage 3: Spatial statistics, analysis, and Simulation.
