We know that the difference between a GIS development kit or a GIS platform and a general graphics system is that the objects managed by it are all spatial references (or geographical references). In short, spatial references are coordinate systems, but the coordinate system is not a simple Cartesian coordinate system, because the earth is a circle. For more information about the relevant documents, see the General cartography textbooks. PairIn GI

Introduction to ucgis priority research areas. Physical Basis of Geographic Information Science:The concepts, classifications, relationships, and evolution of geographies at different scales are studied, including their interactions. Geographic Information Representation:Extends existing data models and structures to represent multi-dimensional spatial entities and processes (temporal). Develops spatial analysis methods, especially for large data volumes and distributed spatial databases.The

Any theme in the material world is firmly branded with time and space. More than 80% of people's production and life information is related to geographical location. Geographic Information System (GIS), as an important tool, technology and discipline for obtaining, processing, managing, and analyzing geospatial data, has received wide attention and rapid development in recent years. From the perspective of technology and application, GIS is a tool, method, and technology for solving spatial pro

It is applied in the global (national or provincial) basic map service or public basic map service, we will find that there are two hidden problems in it, so that the positive axis is equal to the cylindrical projection advantages are not painful, or even become a disadvantage: 1.

According to ArcMap, maps and cartography are divided into two pages, and they are synchronized by sharing the same map object, in the case of the Pagelayoutcontrol pagelayoutreplaced event, Assigning the current active map to Mapcontrol, and then switching between the two, is the basic practice as follows: Private voidPagelayoutevents_onpagelayoutreplaced (Objectnewpagelayout) {M_mapcontrol.map=M_PageLayoutControl.ActiveView.FocusMap; if(m_bis

Temporal data display is a very "charm" of the data display means, such as can be used to dynamically display the color of the changes in the 10-year population change, or with a dynamic point to show the movement of the center of the typhoon, and so on, this animation in the way compared to ordinary cartography can often get a better user experience. Recently did two small demo test the temporal data, here to share with you.The so-called temporal dat

teaching methods, introduce advanced teaching ideas and teaching tools, and teach the new technology of mechanical drawing. Focus on arousing students ' interest, cultivating students ' space imagination ability and applying practical ability of reading graph cartography theory.First, problems existing in the teaching of mechanical drawingAs with the teaching of other disciplines, the teaching process of mechanical drawing also has the disadvantage

1. The Mapcontrol control is a very common control used in Arcobject (Arcengine), which corresponds to the DataView view in ArcMap. Functions implemented by the Mapcontrol control:1) Manage the control's appearance, display properties, and map properties;2) Adding and managing the data layer in the control (datalayers);3) load the map document (MXD) into the control;4) Drag and drop data from other applications into the control;5) Use the mouse to draw the geometry and paint to the screen displa
