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

I had nothing to worry about this afternoon. I accidentally reviewed the mysql manual. I used to check the content of the manual very well, the focus is on some basic details of SQL statements, mysql performance parameters, and storage control management. However, today I accidentally discovered an important feature of mysql, that is, mysql also stores spatial data related to gis. I had nothing to worry about this afternoon. I accidentally reviewed th

2.5 Comparison of vector and raster data structuresEarly in the development of computer-aided cartography and GIS, vector processing technology was originally quoted, and raster data processing began in the middle of the 70 's. A few years ago, these two data structures were hard to be compatible, so they caused a lot of inconvenience to the use of data. In recent years, it has become more and more clear that the differences between grid and vector da

This is an experiment that I did when I first came into contact with the Google map API last year. I didn't do any further work in the future, but I wrote a draft and kept it in my blog post. Although some ideas are naive, there are even some errors. Today it seems that there are still some reference values, so I will release the draft for you to have a look. The original text is as follows: 0. Description After some time of thinking, I recently tried a "Google map online vector Interoperabi

Distance from the last hair has passed seemingly do not know how many days, suddenly found himself lazy summed up. This problem feel bad, but also have to write something to enrich themselves, otherwise this day of the life of the muddle, also too dull, no matter how to say, at least have to leave something for their experience. Gossip does not pull, recently has been busy with the GIS, the main domestic two map: Baidu and Gold maps, do directly call

underground integrated pipeline Geographic Information System of the "Digital Urban Management" Phase II. Through the Shaoxing county Pipeline Data Survey, 17 types of pipeline data have been fully established, and basic terrain data has also been established. These basic data reserves provide a powerful data basis for the establishment of the Shaoxing underground pipeline information system. Our company cooperates with Beijing Supermap software Co., Ltd. to develop and implement the geographic

Openlayers calls WMS Openlayers: Openlayers is an open-source JS framework used to implement Map Browsing effects and basic zoom and Pan functions in your browser. The map sources supported by openlayers include WMS, GoogleMap, kamap, and msvirtualearth. You can also use simple images as the source. openlayers provides many options. WMS service: 1 OGC organization and its open specifications To enable interoperability and integration of heterogeneous geospatial information and

For GIS software, attribute data display is an important issue. In the underlying GIS development based on VC ++, clistctrl or DBGrid is generally used to display attribute data. However, if the display efficiency of these controls is relatively low or the effic

I. Overview Interactive Drawing, I understand, is to draw a graph with the mouse. Interactive plotting is often used in GIS software development and design. For example, ArcGIS and other software have very complex human-computer interaction functions. Interactive plotting occupies an important position in GIS.2. object-oriented modeling of Elements In interactive drawing, you can view the elements of the dr

After creating a scenario in cityengine, We need to export the created model (in 3DS and OBJ formats ). You can select two export modes: Use File size limit and create one file per shape. Use File Size Limit: export the selected model as an OBJ or 3DS file. Createone file per shape: exports the model according to the shape. A 3DS or OBJ file is generated for the model generated by each shape. Figure 1Export Method Next we will discuss the naming of model files when exporting models using the cr
