91 Satellite Map Assistant

91 Satellite Map AssistantIt is the world's first truly professional downloader for Google Earth images, historical images, and elevations. 91 Satellite Map Assistant (Google Earth Edition) is the world's first truly professional downloader of Google Earth images, historical images, and elevations. It perfectly realizes direct downloading of data from the Google Earth server through a complete interpretation of the Google Earth data transmission protocol.

Software features

HD data without watermarks or offsets

Download images directly from the Google Earth server to avoid Google watermarks, and the data does not require correction or reprojection and can be directly used for professional analysis.

It supports downloading of data of any scale and format around the world. The download efficiency is 5-10 times that of ordinary tools, and it supports batch processing of massive data.

Historical image tracing and elevation data support

Provides historical image downloads from the 1930s to the present to meet the needs of time series analysis.

Supports downloading of global high-precision elevation data and directly obtains the entire elevation data to avoid point-by-point sampling errors and achieve higher accuracy.

Multi-format export compatible with coordinate systems

Supports the export of more than 20 formats such as DXF, SHP, CSV, DAT, KML, KMZ, and TXT, and is compatible with industry software such as AutoCAD, ArcGIS, and CASS.

Built-in WGS84, Xi'an 80, Beijing 54, National 2000 and local independent coordinate systems to meet the needs of different scenarios.

Independent operation and IP-free technology

No need to install Google Earth, it can still be used even if Google Earth is blocked.

By interpreting the transmission protocol, IPs are exempted from blocking and unlimited downloads are supported to avoid interruptions caused by IP blocking.
