gis for beginners

I just started to study the secondary development of GIS. I recorded several translation methods in the previous article. Today I will look at the functional code of map enlargement. We also look at several different methods when implementing amplification (triggered in the event of the button, and compiled as DLL by using COM technology and registered to the machine ). The first method is compiled into DLL registration.Code Code highlighting produce

In (2), we analyzed the HTML code, and basically figured out how. Net ADF encapsulates client interaction and how the client interacts with the server. Next, let's take a look at the development method on the server side. It is actually a simple practice. If you can learn about the implementation of AGS when developing Web GIS using other jobs, you will surely be inspired by some tips on encapsulating the client, server, and interaction between the tw

and GIS related conferences outside China, numerous and numerous , there are roughly two types. User conferences and technical branches organized by software vendors or organizations, for example, ESRI Annual international / domestic User Conference, developer Conference, special conferences on various technical applications, educational conferences and academic conferences held by universities or associations, for example, 08 ISPR

Label: hbase GIS This chapter describes how to use hbase to store and efficiently query Geographical location information. Geohash spatial index Consider two common problems in the LBS application: 1) find the nearest K locations; 2) Find the locations in a region. If you want to use hbase for efficient search, you must first consider the space locality (spatial locality), that is, the points close to each other must be physically stored together. Th

Introduction to online web GIS data collection based on Arcgis for Js, arcgisgis In the previous blog, "Conversion between WKT and geometry in Arcgis for js", the conversion between wkt and geometry is realized. The original blog address is http://blog.csdn.net/gisshixisheng/article/details/42657.pdf. In this section, we will briefly introduce online collection of web GIS data based on Arcgis for Js. To ac

I have already worked on two GIS projects. due to tight project time and other reasons, it has always been a heap CodeWithout considering the data structure and AlgorithmAnd does not consider the performance. As you can imagine, the last thing is useless. Looking back, I feel like a failure, so impetuous. Just now I have taken over a GIS project. I plan to take this opportunity to develop and summarize i

The Land Leveling Project is the top priority of the land consolidation work. Although it is often used for budget adjustment during actual operations, it plays a decisive role in the implementation of the project. I. Earthwork CalculationTraditional methods, such as the section method, scatter method, and square method, are easy to understand. There are also some odd names in the north, such as what is inverted and troughs. In summary, none of these methods can be accurately calculated. Curr

Recently in the Unity3d and GIS projects, the most important thing is the transformation of coordinates. For example, the latitude and longitude (166.23.9.27. 39.55.15.74) transitions into unity into a corresponding location point. Don't say much nonsense about the code:Using unityengine;using System.collections;public class Saigetlatlog:monobehaviour {public Transform firstpoint;// Unity in the upper left point public Transform secondpoint;//unity in

The full name of stars is space-time analysis of regional systems, which is a space-time analytical software for regional systems .This is an analysis package for the region's multi-temporal data, and the source code is exposed.The software brings the space-time analysis technology developed in recent years into a friendly user interface, designed to be an exploratory data analysis software.It has to be said that exploratory spatial data analysis (ESDA) has only just started at home, while stars

In the previous article "GIS (five)-complete JS version of Sogou map Basic Interactive search function", introduced sogou map keyword search function, today to achieve another important function of it-that is the surrounding search function.In accordance with the Convention, the official online sample code is posted to everyone. The plane ticket is here. Peripheral search function, and keyword search is actually the same, is the main use of the Search

For the development of AE really do not interest, want to do a good job JS development, but this course to test, but also to do a design. So I decided to make this development before the design week came. And then you can have the tricks. Mainly through the blog can urge themselves to engage in, can be completed as soon as possible. Demand Analysis1. Basic map Operation function. Eagle eye view between left and right windows.2. Basic query and statistical functions. Queries that include properti

Since the invention of paper, human beings have used paper maps to represent geospatial information for thousands of years. After the emergence of the computer, people began to use discrete and topological relationship between point strings in the computer to describe various spatial elements of points, lines, planes, and bodies. This led to the emergence of digital maps. With the development of information technology, digital map is no longer the only way to express geospatial data in computers
