ArcGIS image solution (I)-expansion of Chinese satellites

In ArcGIS image solution, SP2 patch and ArcGIS Server 10.1.2 (required for domestic Image Service Release) must be installed for the expansion of Chinese satellites ).

1) Domestic satellite types supported by image Extension

Supported types can be viewed when rastertype is selected when addraster is added to the embedded dataset.

 

Currently, the raster type supported by Chinese satellites and simple parameters are described as follows:

Rater type name	Spatial Resolution	Description	Remarks
HJ 1A/1B CCD	Multi-spectral: 30 meters	Environment Satellite CCD Product	HJ-1A star is equipped with CCD camera and hyper-spectral imager (HSI), HJ-1B star is equipped with CCD camera and infrared camera (IRS)
ZY1-02C (PMS)	Multi-spectral: 10 meters Full Color: 5 meters	Resource 02c satellite PMS sensor products	Configured 10-meter resolution P/MS multi-spectral camera
ZY1-02C (HRC)	Color: 2.36 meters	Resource 02c satellite HRC sensor products	Two 2.36-meter HR cameras configured
Zy3-CRESDA	Multi-spectral: 6 meters Full normal shooting: 2.1 meters Full-color preview: 3.5 meters Full-color postview: 3.5 meters	Resource 3 stereo ing satellite images distributed by the Resource Satellite Application Center (CRESDA)	The Resource Satellite Application Center (CRESDA) and the satellite ing Application Center (sasmac) are responsible for data distribution of resource 3 satellite. Since the two units distribute different image product specifications, so create ZY-3 CRESDA and ZY-3 sasmac respectively.
Zy3-sasmac	Multi-spectral: 6 meters Full normal shooting: 2.1 meters Full-color preview: 3.5 meters Full-color postview: 3.5 meters	Resources distributed by the satellite ing Application Center (sasmac) No. 3 stereo ing satellite images

 

2) supported Functions

After the extension is installed, you can display, analyze, process, and manage the above sensor image products in ArcGIS. You can create a live and integrated mosaic dataset, crop images, publish image services, and create image caches and slices Based on boundary.

It mainly involves the following functions:

1) ZY-3 sasmac level Level 1 data can be dragged to ArcMap to realize geometric correction of single scene multi-spectrum, full color, front view, back view image data;

2) ZY-3 sasmac multi-spectral Data Based on DEM correction;

3) The fusion of ZY-3 level1 multi-optical spectrum and full color image, because there is a 6 degree angle between the ZY-3 multi-optical spectrum and the full color sensor, ArcGIS does not provide the image fusion template of ZY-3 raster products, need manual fusion;

4) Management of Chinese Satellite Images Based on Embedded datasets, including management of multi-spectral and direct-image fusion images; provides management methods and steps for level2 or level3 products based on table and raster layer;

5) create the image service of ArcGIS Server and publish the image slicing service of ArcGIS online;

3) Considerations

During the actual operation, if the data path string is too long, the statistical information of level3 level data will be saved in ***. TIF. aux. XML files) are lost, the number of files is not missing, but the file size is smaller. The problem does not occur when you add a single image and perform multi-optical and full-color fusion. However, when you create an embedded dataset and add a grid, the image is black because there is no original statistical information, level3 data can be copied separately.
