Who knows what GIS is?

Harbin Chengtong Digital Information Technology****.

Harbin Core Technology Development ****.

Harbin Jintu software development****.

Generally, land, surveying and mapping departments use it more.

The most common ones are ArcGIS and Mapgis

Our company is engaged in GIS application development, mainly using mapinfo

ArcGIS still needs to be learned, and it is more extensive. MapGIS is used less, and mapinfo is used in some provinces.

The above 3 software land is used a lot, and CAD and CASS are generally used for surveying and mapping. The software used by each department is different, according to the actual situation, like the previous unit used more mapgis, now this unit is basically 3 do not use, 55555...

I have a good understanding of geography, and GIS is one of them.

As follows: 1. Consider hobbies first: the major direction of geography is divided into three branches:

Physical geography (research directions include hydrology, geomorphology, climate, biology, peat, etc.), human geography (research directions include urban planning, regional economy, population resources and environment, etc.), geographic information system (research directions include maps, remote sensing, GIS, etc.). The landlord is studying economics, and it is initially recommended to consider human geography, of course, the other two branches can definitely be studied. The specific test subjects are different and the schools are different, so it is recommended to consult further and be targeted.

2. Consider from the aspect of employment

1. Middle school teachers (junior high school and high school geography teachers).

2. University teachers (urban and rural planning, tourism, most of them require a bachelor's degree or above in geography).

2. Institute of Urban and Rural Planning (most of them require a master's degree or above in geography, mainly in urban planning, geographic information system, etc.).

3. Department of Land and Resources (Bureau) (most of them require a master's degree or above in geography, mainly in physical geography, urban planning, remote sensing mapping, etc.).

4. Companies (such as the well-known Beijing Supermap Information Company, most of which require a master's degree or above in geography, and the research direction is mainly urban planning, geographic information system remote sensing mapping, etc.).

5. Department of Hydrology and Water Conservancy (Bureau) (most of them require a bachelor's degree or above in geography, mainly in physical geography, physical information systems, etc.).

6. Environmental Protection Bureau (most of them require a bachelor's degree or above in geography, majoring mainly in physical geography, and the research direction is comprehensive geogeography, etc.).

7. Meteorological Bureau (most of them require a bachelor's degree or above in geography, majoring mainly in physical geography, and the research direction is climatology, etc.).

8. Research institutes (most of them require a master's degree or above in geography, and all majors are required).

9. Other employment directions (which I have not yet learned).

GIS has broad prospects, whether it is into a public institution or a company, the development has been good in recent years. Personally, I think GIS is the best one to employ among the three majors.

Hope it helps!

Personally, I feel that in recent years, the domestic GIS is developing, and the development speed is very fast, now the employment rate of our professional graduates is higher than a year, we have many students who graduate from surveying and mapping, data processing, secondary development, and surveying and mapping instrument sales, do surveying and mapping and secondary development generally have work experience The salary is very high, do data processing and sales do not need work experience at all, and the annual salary of data processing should be 2 to 50,000 yuan after graduation, depending on the unit, If you are very good at sales, the income will be higher, if you do not reject this profession, I advise you to persevere, and the future will be better and better.

Convert the dwg format to the dxf format file and convert it to the dxf format; Use the import in the mapinfo software to convert the CAD file to the tab format in the mapinfo software; Then use the export method in mapinfo to export the tab format to the mif format; Use the file conversion function in MapGIS to convert the MIF format to point, line, and area files; There are too many points in the line file converted above, you can use the line extraction function to reduce the line points, and I use the thinning factor; mapinfo only needs its generic converter.

1.Save the CAD file as 2004DXF format 2In the GIS main program, select "File Conversion" 3 input, select load DXF file, OK and reset 4 Save dot line file, the above is the basic step of my conversion, but I just can't transfer it.

Please take a look at what is wrong or what is missing. Thank you.

If you don't convert the layer, you don't want to go to mapgis, and you can't tell why you can't go through it without you talking in detail.

You can try it in GIF format, and it should be fine. View the original post

First of all, you must know that the scale of your picture, but also know the longitude of the projection center point, which is the original projection parameter to be set in the projection transformation, and the result of the projection parameter is to select the geographic coordinate system first, and Beijing 54 can then choose the degree minutes and seconds. It's simple.

The screen coordinates cannot be projected, and the screen coordinates of the drawing must be moved to a position that matches the surface coordinates before the calculation can be performed. Knowing that the surface coordinates can be projected and transformed, if you only want numerical values, it is recommended that the landlord use coordinate conversion software to convert them wholeheartedly.

The xy in mapgis is converted to latitude and longitude??? This one.

Oh, got it, that handsome guy gave me a coordinate conversion software.

The elevation is just a property of the line, it should not affect the graphics of the two-dimensional plane, it doesn't matter if there is a displacement, after the conversion, use the error correction, just correct it, if the elevation is to be changed, use automatic elevation in mapgis, and start again.

You can see if the problem with the number causes the wrong location! Of course.

If you know the specific (xy) coordinate position, you can change the whole map in mapgis, and you can change it to the correct coordinates.

Specifically, in general, the conversion will not be offset in the past.
