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
In ArcGIS 10.1, ArcPad axf reader is added to allow users to directly use the data interoperability extension module.Read the contents of the ArcPad axf file until ArcGISBefore the official release of 10.1, FME provided a temporary free license for FME ArcPad data interoperabilityedition to read ArcPad axf data, which is included in ArcPad 10 SP3 and later versions.

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.

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

The concept of semi-Supervised Learning (semi-supervised learning) is not complex at all, that is, a centralized learning model for training that contains both labeled data and unlabeled data. Semi-Guided Learning is a machine learning method between Guided Learning and unsupervised learning.
In many tasks in the NLP field, it is difficult to obtain labeled data. In particular, training resources such as sy

Without expensive annotations, it is easier to train the model with synthetic images. However, the effect of synthetic image is not satisfactory because of the difference between the distribution of synthetic image and the real image. Therefore, "Analog + unsupervised" (s+u) Learning: Keep The annotation information given by the
