I first exposed to SuperMap Object, I wrote this time to let everyone experience it, this is my first time in writing articles, write bad, please forgive me, please give pointers.
Prior to this, let's understand what is component GIS. GIS (Geographic Information System is a tool for processing spatial data. It shortens the development cycle of spatial data and improves development efficiency.
SuperMap Object is a component GIS development platform based on ActicX / COM technology development, which provides a series of components, including core component libraries SuperMap.ocx, layout component library superLayout.ocx, 3D component library super3d.ocx, topology Component Library SuperTopo.ocx, Legend Component Library SuperleGend.ocx, Properties Table Component Library SupergirdView.ocx, Auxiliary Component Library SMXassistant.ocx, Encrypted Lock Information Component Library SMXLockInfo.ocX, Workspace Component Management Component Library SuperwkspManager.ocx.
Some basic concepts of SuperMap Object:
Workspace: Used to store a collection of all data, including data sources, map names, layouts, and resources.
Data Source: Places for storing space data.
Dataset: It is the basic unit that makes up the data source. A data source can consist of multiple different data sets.
Layer: The data set displays information on the screen through the layer, in general, one layer only displays only one dataset.
Layout: Plus one or more maps (picture names, graphics, etc.) on the layout window in place.
Recording set: The basic unit of the store is stored, where the stored information includes geometric fields and attribute fields.
Geometric objects: including geometric graphics (points, lines, faces, etc.) and text.
Because it is the first time to contact SuperMap Object, it still feels hard to get this thing. I will continue to send me to everyone later.
