Yesterday, after a few hours of study. The MapReduce learns the first stage of a certain bit of the method. That is, when most files begin with data to Key-value cartography. That's the process of InputFormat. Although the process is not very difficult, but there are very many details.It's very rare for anyone to do a more nuanced study of this. Learn. Today. Let me give you an analysis of the principle of this piece of code.I also spent a little time

-cartography and computer graphics. Therefore, the existing data models, whether it is an object model or a domain model, it is not the information of the real world, but the visualized parameters of some of its properties (basic, not completely). Therefore, problems such as system interoperability and Data Metadata cannot be well solved. Therefore, the concept of semantic GIS is proposed. Then, the relevant research and implementation are probably

2.5 Comparison of vector and raster data structuresEarly in the development of computer-aided cartography and GIS, vector processing technology was originally quoted, and raster data processing began in the middle of the 70 's. A few years ago, these two data structures were hard to be compatible, so they caused a lot of inconvenience to the use of data. In recent years, it has become more and more clear that the differences between grid and vector da

First say the effect:Before generating the contour:After creating the contour mask, the effect is as follows:Steps:1. Getting ready: Open the Toolboxmenu, geoprocessing, ArcToolbox2. Find cartography tools, masking tools, Feature Outline masks3. Select input layer and output Feature Class. Reference scale generally fill 1.Then adjust the contour distance margin, here I need 30 meters contour line, so fill in the meters can.4. Click OK to wait for the

This is done by analyzing the personal results file here, which is the basis for our custom charts, which is to import the timing data into Excel. Similarly, Excel files are uploaded to blob storage for greater resiliency and ease of access.The result of this run at the end of each set of t

, select Data-export Data, under Output raster, select Use Renderer, you can convert the image to the unsigned 8 BIT integer cell type storage.By converting the cell type, the image file size is reduced to around 30G. On this basis, the MRSID compression, the final national 30 meters resolution of the Hillshade data size of 680M.　　Iv. SummaryTaking the national 30-meter resolution Aster dem as an example, this paper describes how to make a high-quality, small data volume of the mountain Shadow.

Original ArcMap custom Scripting tool AuthoringIn the early stages of cartography, the general need to do some data collation, layer merging, cutting and other work. While there are tools available in ArcMap, it takes a bit of skill to use them. such as batch cropping, although it can be achieved, but the results will be renamed to [layer name]_clip, so for the configuration of the entire area of MXD, it is very unfriendly to cut part of the range of
