digitizing map的意思|示意

The accuracy of flood area is mostly dependent on the contour interval of map, accuracy of digitizing map, accuracy of DEM, and interval of GRID, detecting resolution of pixels.

对于采用本方法计算淹没区，准确性受地形图等高距大小、数字化采集精度、数字地面模型（DEM）高程精度以及格网间隔大小、像素探测分辨率等因素的影响。

The methods to obtain the Digital Terrain Model (DTM) from contour map by scan digitizing were studied.

本文还研究了通过扫描数字化等高线图建立数字地形模型的方法。

The steps for the system establishment include digitizing the forest types map and topographic map and linking the attributes of forest types and spatial information.

该系统的建立包括林相图、地形图的数字化与处理，小班属性与空间信息系统相联结。

And three geometric correcting methods are provided for correcting the error originated from the digitizing and the map paper's distortion too.

同时，给出了三种几何纠正方法来纠正数字化和图纸变形产生的误差。
