tools for geographic datasets and applied to these datasets. Geographic data sets can be raw measurements (such as satellite images), Information parsed and compiled by analysts (such as roads, buildings, and land types ), you can also use analysis and model operations to obtain information from other data sources.

and some problems. They do not have to assign technical personnel to help us solve them, even if the problem can be solved, it is also a daily price. 2,AMAP/tiger Map-- This is also the two famous map companies in HUO. They are closer to us than Baidu Google, and there will also be related secondary development. However, it is also because Huo is famous that they do not lack projects, there is no shortage of partners, so the price is still very high, suitable for large state-owned foreign compa

This article mainly introduces how to use C # to develop geographic information systems with ArcGISEngine. ArcGISEngine allows programmers to create custom GIS desktop programs on Windows systems.

These days, when you do an iOS project, you need to navigate to get the name of the current city. Baidu Map SDK has this function, but in order to not rely on third parties, here use iOS comes with frame corelocation to achieve this requirement. After iOS8 out, for positioning needs a little more processing, can be normal positioning.Aside from this: Many social, e-commerce, group buying applications have introduced maps and positioning functions, and map functionality is no longer unique to map

Mathematics Institute? The answer is self-evident, but why can no one stand up and shout "stop "? Previously, it was said that GIS in China is "platform and department fly together". Although this is not good, it is always several times better than the current "Research and metaphysics. Although the former is not good, although it wastes the joint property of the majority of working people, it can create MapGIS and Supermap, which can make the market share of domestic GIS

integrating computer science, informatics, geography, and other sciences, with the support of computer software and hardware, it uses the theory of system engineering and information science to scientifically manage and comprehensively analyze geographical data with spatial connotations, to provide spatial information

Software is nothing more than "useful and easy to use". On this basis, if the software is more adaptable and you don't have to pay another fee for adding a field, it would be better. Currently, the most popular ERP system, from the actual situation, is to spend more money to buy a decoration, even in the most basic static data management, it cannot satisfy the En
