WINDOWS8 new Geo-location geo-positioning function. WINDOWS8 based on IP address positioning, accuracy of about 25-kilometer, system positioning services do not provide orientation, height, speed, address and other data. When you need to use the positioning feature, you need to display the prompt user, and you can turn the positioning service on or off in Control Panel. Operation Steps 1, use the combinat

First of all, the failure of this attempt belongs to the kind of death on the way to the hospital. Based on the augmented reality of geo-positioning, AR holographic Reality, is a tall on the argument that the straightforward point is a cottage similar to casually go such applications. Open the app, search for surrounding information, and then overlay the information on what the camera has captured. Idea: Use mobile phone to control the Camrea in un

Because the structure of the satellite data (HDF data) is different from that of geotif, you must pay special attention to it when reading the data. Geotif data is generally a file that contains data in multiple bands. While while the modemis, a file contains multiple subdatasets. Gdal. Each subdataset contains multiple band data. In addition, the default compiled gdal does not include support for the modem_data. You need to download the source code for hdf4 and hdf5 separately, and then modify

The dataset is the central concept of ADO. Datasets can be treated as an in-memory database, which is a separate collection of data that is not dependent on the database. The so-called independence, that is, even if the data link is disconnected, or shut down the database, the dataset is still available, the dataset is internally XML to describe the data, because XML is a platform-independent, language-independent data Description language, and can de
