Description
Technical field
The present invention relates to a kind of instructional device, more particularly to a kind of indoor digital mapping teaching platform device.
Background technology
It is core under the support of external input-output equipment that digital mapping, which is using computer and its software, to topographic space
Data are acquired, input, Cheng Tu, drawing, output, management.
Colleges and universities take outdoor, field teaching mode when carrying out digital mapping teaching at present, after collection in worksite data at
Figure.
But outdoor mapping teaching climate condition is affected, and rainy season measures Practical Courses in outdoor, and process is often by under
The influence of rain, often takes shelter from the rain back and forth, and hardly possible completes normal teaching, and teachers and students drench with rain, and health is also impacted；Heat day is in outdoor
Teaching, the factors such as the heat absorptions such as road concrete, pitch reflection add weather reason itself, and live temperature is high, teacher, Xue Shengdou
Soaked with sweat, most students are difficult to focus on, and teaching efficiency is very poor.
Outdoor mapping teaching is also by school's natural conditions（Building, massif, road etc.）Constraint, natural conditions, building
Single, many atural object dispersions lack；Region area is big, and personnel's relative distribution, teacher's guidance gets up very inconvenient.
Invention content
The technical problem to be solved by the present invention is to：Digital mapping can be carried out indoors by providing one kind, both ensure that whole day
The digital mapping of time is imparted knowledge to students, while also greatly improving the indoor digital mapping teaching platform device of teaching efficiency, is solved
In place of above-mentioned the shortcomings of the prior art.
Solving the technical solution of above-mentioned technical problem is：A kind of indoor digital mapping teaching platform device, including it is used for mould
Intend the sand table of actual landform and landforms, as multiple prisms of positioning atural object mapping target and for disposing the multiple of total powerstation
