Embodiment Construction

[0018] Click the Arcgis toolbox ArcCatalog, click the right mouse button and select New Python Toolbox, and name the toolbox. We name it here Remote Sensing Image Information Extraction Toolbox.pyt, then click Edit, and paste the prepared Python code into it. , the specific code is as follows.

[0019] The algorithm to realize the interface is introduced:

[0020] The completed function is to import the module and retrieve the specific extension module license, give the toolbox a name and define a list of all tool classes, as follows:

[0021]

[0022]

[0023] Let's take a look at how to implement each function with an example of night light data.

[0024] 1. Batch copy raster data (BatchCopyRasterData)

[0025] This tool can be used to scale a pixel type from one bit depth to another. When scaling a pixel depth, the raster displays the same bit depth, but the values ​​are scaled to the new specified bit depth. BatchCopyRasterData can copy the image according to the ...

Abstract

In the invention, a toolbox which can be nested into Arcgis and extracts remote-sensing image information is developed on the basis of a python language. At the same time, nighttime lamplight (DMSP / OLS) data instances are combined to illustrate how to apply the toolkit in practice for extraction. The toolbox of the invention includes batch copying of raster data, batch export of attribute tables and batch use of a dichotomy for extracting urban boundary thresholds. According to the toolbox which is of the invention, is developed by virtue of the python language and can be nested in the Arcgis,artificial processing which is low in efficiency and liable to errors is avoided, data quality can be guaranteed, repetitive labor can be reduced, efficiency can be improved, and operations are convenient and feasible.

Description

technical field [0001] The present invention relates to the field of remote sensing / geographical information system, in particular, to the extraction of remote sensing image information. Background technique [0002] In related technologies, when the amount of raster data of remote sensing images across periods is relatively large, batch processing is usually used to solve the problem, but it is inconvenient to use for researchers who are not familiar with programming languages. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a toolbox, which can batch process remote sensing data and can be called in Arcgis. What's more, the user only needs to click on the relevant functions in the toolbox to operate, which is simple and easy . [0004] The toolbox for batch processing remote sensing data implemented accordi...
