Recently in doing Unity3d and GIS projects, the most basic is the conversion of coordinates, such as the latitude and longitude (166.23.9.27, 39.55.15.74) into unity into the corresponding location points, nonsense not much to say on the code:usingUnityengine;usingSystem.Collections; Public classSaigetlatlog:monobehaviour { PublicTransform Firstpoint;//top left point in Unity PublicTransform Secondpoint;//bottom right point in Unity Public

applications, I added a layer, that is, the real-time drawing layer, the distance measurement, area measurement, angle measurement and so on the layer, so that the map refreshThe time to redraw the data is not much, improve the performance of the program.First on a diagram, I am currently doing a simple GIS framework (just to meet my current needs, the main feature is fast). As shown in.Initial completion of the above framework design, I got the abov

Service Area Analysis is mainly an analysis concept in commercial site selection. It analyzes the service scope of a mall. In urban planning, it is mostly used for the service scope of public facilities. Besides considering distance and spatial accessibility, there are also the attractiveness and service capabilities of public service facilities, that is, the gravity model is used. In regional planning, we also use the gravity model to consider the distance and the city's own indicators for calc

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
