The client is not able to issue a play request until a successful answer to the setup request has been received. The play request navigates the normal play time to the beginning of the specified range, and transmits the data stream until the end of the playback range. The play request may be piped (pipelined), which is placed in the queue (queued), and the server must put the play request into t
Satellite remote sensing data is an important part of the Geographic Information System database. Using it as the basic data source, Data Interpretation marks are created based on its attribute information to extract basic geographic information data. If we further analyze and study other information related to satellite remote

1, Beam IntroductionIn order to serialize HDF files in Hadoop, after a variety of searches, inadvertently discovered a powerful Java open source software, it is beam.For researchers engaged in remote sensing, it can be used as a powerful open source remote sensing processing software by installing beam. Although not en
Images with a spatial resolution of less than 1 MB can accurately reflect the detailed information on the surface of collapsed houses. These images are the main data sources for obtaining information on collapsed houses after disasters and play an important role in disaster reduction and relief. Manual visual interpretation and change detection are the main methods for extracting collapsed houses through high-score images. However, the implementation efficiency of this method is difficult to me

Let's take a look at the application of OpenCV in Python programming, let's deal with simple meteorological calculations, write a script using the OpenCV library in Python to calculate the reflectivity of a batch image, and try it out.
The core step is the remote sensing image spectral radiometric calibration → atmospheri
The rapid development of remote sensing technology provides people with a lot of information about the Earth's space, however, making map cache is a very time consuming work, according to the traditional method of cutting and caching, the image data cannot be used in time, that is, the timeliness is poor; the slicing process is frequent, difficult to manage and requires strong hardware support. , the large

We know that the classification of remote sensing is uncertain, and its uncertainty is closely related to the evaluation method chosen. This paper mainly introduces four aspects, firstly introduces the development of the classification accuracy evaluation of remote sensing, and then introduces the evaluation method of
Python uses OpenCV library for simple meteorological remote sensing image computing.
The full name of OpenCV is Open Source Computer Vision Library, which is a cross-platform Computer Vision Library. OpenCV is a product launched and developed by Intel. It is issued with BSD license and can be used free of charge in the commercial and research fields. OpenCV can be used to develop real-time image processing,

Gdal is a database for reading, writing, and reading data from grids and vectors. It has a huge application in the GIS industry. Remote sensing images are an important type of our spatial data, the following code reads and displays remote sensing data:

In MATLAB for image processing, the general use of the image local coordinates, in the upper left corner (at the beginning). When processing is complete, if you want to display the results in a remote sensing image with geographic coordinates, or if you need to output a SHP file, you need to involve conversion of local coordinates and geographic coordinates, and we can use the Pix2map function to implement
