First, prefaceGdal has a powerful image reading and writing function, but the integration of common image processing algorithms is less, OPENCV just has a strong image processing ability, so the effective combination of both the image (remote sensing image) processing brought great convenience. So how to realize the data exchange between Gdal and OpenCV becomes the key step in image processing. Next I'll re

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: Char * szfilename = "K: \ provincial/municipal map \ new folder (2)

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

The remote sensing data provided on the Internet is a lot of nonsense. The addresses I recently used may not be complete, but they are absolutely usable: Http://www.csdb.cn/ This is the site of the Chinese Emy of sciences, the data is very good, the speed is very fast, there are a variety of geographic and chemical data, remote

The Dead Zone of telemetry, that is, the threshold value of telemetry change, is the standard value used to determine whether telemetry is changed. The size of the remote sensing dead zone is not set at will. Although theoretically set to 0, it can be reflected as long as there are slight changes, this is not the correct method. The setting of the telemetry dead zone requires a comprehensive consideration

How to Use Hadoop MapReduce to implement remote sensing product algorithms with different complexity The MapReduce model can be divided into single-Reduce mode, multi-Reduce mode, and non-Reduce mode. For exponential product production algorithms with different complexity, different MapReduce computing modes should be selected as needed. 1) low-complexity product production Algorithms For the production

During geometric correction of remote sensing images, automatic point matching in the control point database may be used. There are many types of control point slice matching algorithms. The most basic classification can be divided into pixel-based vertex slice matching and feature-based vertex slice matching. Because feature-based algorithms are difficult, generally, pixel-based data is used. First, we wi

Someone asked me the day before yesterday. I don't know yet. I saw it on the Forum and added it to my favorites. Haha Scale and resolution of Remote Sensing Images The image resolution rate is an important indicator for determining the image accuracy. The image accuracy must meet the image recognition capability and accuracy requirements of the corresponding scale map update, and the map update cost must al

Previously, I only knew how to export the image data. After saving the image as ASCII, I could export the image in the data format. However, the exported data is output in the form of a matrix of the row and column numbers of the image, to convert to one dimension, this method obviously does not work. As a netizen told me, I know that we can still do this. Next I will introduce how to do this. First, ENVI is used to open the remote

The two cameras photograph the same target from two points at a certain distance. The overlapping images are called stereo images. A necessary condition for a stereo image pair is that the image overlapping degree is greater than 53%. Two remote sensing images will be arranged side by side. If the left eye looks at the image on the left and the right eye looks at the image on the right, it will produce the

Geographic raster (remote sensing images, Dem, scanned images, etc.) is an important data source in GIS. A large amount of raster data is generated every day, but the image itself only records the information of the image, if you want to establish an association with the actual geographic coordinates, you must specify the coefficients of the affine transformation. This is the most commonly used method for g
