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

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

1. GDAL and OpenCV2.X data conversion (suitable for multi-spectral and high-Spectral Multi-Channel Remote Sensing Images), gdalopencv2.x I. Preface GDAL has powerful image reading and writing functions, but has little integration with common image processing algorithms. OpenCV has a strong image processing capability. Therefore, it effectively integrates the two functions for images (

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
