Before reading this article, you should first have an idea to use arcengine to develop C/S applications, A mature GIS project cannot directly organize the data in the SDE in the form of mxd in terms of data loading. This is unscientific for the following reasons: 1. Data security considerations An mxd document contains detailed information about mxd data in the SDE database. Generally, the data owner does not want the information to be obtained fr

1. Can we support massive multi-source spatial data, especially Vector Data? 2. What is the direct support capability for spatial databases such as ArcSDE and oraclesptail? 3. What is the support capability of 3D building models? 4. Is a wide range of data updates fast and efficient and requires preprocessing? 5. What is the technical level of data transmission and display on the platform? Is it smooth? Is there drift jitter and Rasterization? 6. Is it possible to achieve comprehensive and integ

, projecting the shape on the spherical surface onto the cylinder, and then expanding the cylinder, which is a world map drawn by the standard parallels for the "Mercator projection" of zero (that is, the equator). Refer to http://blog.csdn.net/mygisforum/article/details/13295223 This projection method ensures that the meridians and parallels are parallel and perpendicular to each other, are they familiar? However, the greater the deformation of this projection method to the polar ar

example, when two graphs are stitched together, the boundary line and type are compatible. Consistency (consistency): the degree of uniformity in the expression of the same or similar phenomenon. Completeness (completeness) Availability (Accessibility): Refers to the ease with which data is acquired or used. Current issues (timeliness): The index reflects the extent of the current state of the objective phenomenon. Structural transformations (lots of computer graphi

The Chinese nation is an ancient civilization with a history of five thousand years. The family tree is the most important cultural heritage of the Chinese people. It must be inherited and carried forward continuously. Genealogy GIS is people-oriented, family-based, and reconstruction of Chinese civilization over the past five thousand years from the perspective of time and space. Developed by Nanjing Normal University's Key Laboratory of virtual g

If you have been a GIS expert about roadway labeling, please go to Delphi/Windows SDK/API. Http://www.delphi2007.net/DelphiMultimedia/html/delphi_20061110114755162.html I have drawn a tortuous roadway (which can be regarded as an irregular line). How can I name this roadway? Clearly drawn on the roadway? All words are distributed in a straight line according to the general trend, which is in line with people's cognitive habits. I also know how

In our GIS development, in order to better display and display spatial data, we often need to draw symbols. circles are often used as positioning classification symbols on maps, the center of the circle is located at the center of the element. The area of the circle indicates the corresponding number of indicators. In a computer, the circle is approaching by a polygon. When the number of sides of a polygon reaches the ground that cannot be distinguis

Select the open-source SharpMap. SharpMap is a Map rendering class library developed based on. net 2.0 using C #. It can render various GIS data (currently supports ESRI Shape and PostGIS format) and can be applied to desktop and Web programs. Its URL is: http://sharpmap.iter.dk/ The SharpMap License is GNU General Public License and the developer is Morten Nielsen (http://www.iter.dk /). The current stable version is 0.8 (9.0beta has been released

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

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
