Dem is often used in daily applications of data, to fill in the excavation analysis, three-dimensional scene display, image map of the correction, hydrological analysis and so on. As a result of projects or projects we need to buy some dem, where *.dem is the most common form of DEM, *.dem has two formats, NSDTF and USGS.
If it is the USGS format dem, it is very good to do. Can be read directly through

This article focuses on the transformation of geometry types between the common APIs in the Web ADF and the various specific APIs.1 There are several conversions, the three parties involved:The geometry type of.

Chapter 6 JVM garbage collector (2) jvm garbage collection
The previous chapter records several common garbage collectors. For details, see chapter 5 JVM garbage collector (1).
1. G1
Note:
From the Perspective, compared with CMS, G1 is different only in the final "filter and recycle" section (CMS is a concurrent cleanup). In fact, the overall heap memory division of the G1 recycler is different from tha
Garbage collection mechanism in JavaAn important feature of Java is the garbage collector, and the ability to automatically recycle garbage, which is the advantage of Java relative to other languages, such as the C language there is no automatic garbage collection mechanism.Every instance object and array in Java allocates space within the heap, the interpreter has the ability to allocate space for the class instance, and when the interpreter allocate
