In this tutorial, the third section describes the attributes, geometric figures, and coordinate systems of the FME Element Object fmeofeature. Chapter 3 is the basis of this chapter. This chapter describes more and more powerful element processing functions.
When introducing element processing, it is necessary to distinguish between element-based processing and set-based processing. element-based processing refers to the independent elements of o
For GIS, a two-dimensional coordinate system is a plane reference grid used to measure the distance. A three-dimensional coordinate system is used to measure the distance in a three-dimensional space. A coordinate system is generally defined by map projection, an elliptical body and a datum, one or more weft wires, a central meridian, and horizontal or vertical displacement. Concept data model of the coordinate system of the FME object:
For the con
Fmeofeature is a feature object and is an FME object application.ProgramIn general, the element is a set of attributes and a ry associated with the coordinate system. When an application reads data from a dataset, it reads the element data one by one, when an application writes data to a dataset, the elements can be operated by all standard FME functions and processors. The following is the Logical Data Mod

The gfme object API contains the following collection objects:
Fmeostringarray, fmeofeaturevector, and fmeorectanglevector.
These objects are mainly used to move data. For example, as a parameter or return value, these objects are not used to replace the set in VB.

Note: The read and write operations on the FME object depend on the Reader/Writer row in the preceding table.
The second parameter of createReader is a Boolean value used to determine whether to create a feature disk cache. If your application needs to access the feature set multiple times, it will cache to improve performance, multiple accesses to the dataset cache can reduce I/O requests, create a disk-based spatial index for the
A process was recently tested:
1. Use tepro to create a vector layer and save it to the SHP format;
2. Use FME to import the SHP file to Oracle Spatial;
3. Release vector layers in Oracle Spatial into WFS-T services through SFS;
4. Load the WFS-T Service released by SFS through tepro, edit and other operations, and save the results directly to the Oracle Spatial service;
* When using the vector database and the release map service, pay attentio

PHP is a scripting language that requires the PHP interpreter to parse and run PHP files. When PHP is used as a CGI service Web request, it needs to be embedded in some kind of Web server, most commonly integrated into Apache or IIS, that is, before using PHP, you need to install Apache or IIS, and correctly configure them and PHP integrated parameters. Although this configuration is already very prescriptive and the documentation is very rich, we oft

Many corporate LANs now have their own file servers for storing or sharing files for use by local area network users. However, in the process of setting up shared file access, it is common for shared files to be randomly copied, modified, or even deleted, which makes the security management of shared files face a greater risk. How can you make it possible for users to access shared files and prevent improper operation of shared files? I think that can be achieved through the following two ways:
