Android GIS Development Series-Introductory season (5), in this article, we know how to find features. Now there is a need to find a point 5000 meters in the range of features, then how to do it? First we need to draw a circle with a radius of 5000 meters on the map and then query the relevant features based on the queryparameters. Specific as follows:One, draw a circle with a radius of 5000 meters1. Determine the center point: centerpoint2. Radius of

Objective With the rapid development of information technology, GIS technology has been developed, which has created a new model for the management of geo-information. It is used more and more widely. Of course, this is not the stuff discussed in this article!! Introduced This article refers to the symbol from ArcGIS, so only for the GIS has a certain experience of friends and I learn together. Main refe

The rise of mobile has provided great convenience to the dynamic aspects of planning, all kinds of the deep development of wireless terminal,

Due to work reasons, I have been studying the controls of GIS over the past few days. I mainly read the controls of Supermap and MapInfo. The main achievements are as follows: 1. Most GIS controls have these controls: mapcontrol is used to display maps, zoomin, zoomout, roaming (used to drag a map), moving left, and moving right. 2. I watched some flash and some examples and found that the main functions

1. PrefaceThis week, I did some preliminary exploration of open source software and related technologies and processes involved in the open source solution for GIS, as well as some of the more mature cases that other companies have done with open source solutions. Here I will some technical key points of the preliminary research to do a summary, while the other companies open source success stories to do an analysis, and put forward the personal think

The GIS business development stage is divided: Phase 1: digitalization. At this stage, people are new to GIS. The main business is to digitize previous data;Stage 2: visualization. The user uses spatial data for two-dimensional drawing and three-dimensional roamingCodeConvert to images that are easier to accept and perceive;Stage 3: Spatial statistics, analysis, and Simulation.

focus on investment and policy inclination. The discipline construction is intensifying. This subject has a long history. As early as the beginning of 1950s, Professor Lu Shufen, a famous Chinese cartography artist, set up the teaching and research base for cartography. In 1980, Cartography and Remote Sensing became the first master's degree authority approved by the State Council. In recent years, the provincial department of education and schools have attached great importance to the developm

terms of style. Udig is easy to use. The advantage is that when the map service is released and you want to modify the style of a layer, you only need to modify the style that was originally referenced, you do not need to re-release the layers. The installation package (ms4w.zip, decompress to the root directory) of mapserverhas built-in Apache. However, because IIS occupies port 80, you need to set the following port (In \ ms4w \ apache \ conf \ httpd. in Conf, change Listen 80 to listen 8081

Because embedded systems and general PC systems differ greatly in computing speed, memory capacity, and storage space, how can GIS engines run well on embedded devices, you need to optimize the following aspects: 1) Data Organization 1. Map Data Compression (curve extraction) There are usually a large number of vertex Vertex on the line and plane data. Because vertex is too dense, it takes too much time to draw. Therefore, map data must be pr
