Kawm hauv chav kawm ntawm GIS Tus Kws Paub: ArcGIS, gvSIG thiab QGIS. 

Kawm li cas los tswj peb qhov kev xav tau thiab thev naus laus zis GIS cov neeg hauv kev lag luam hauv ntiaj teb.

Qhov no yog ib tug ua kom tiav cov hoob kawm nyob rau hauv uas koj kawm ua hauj lwm nrog GIS raster thiab vector, projections, topology cai, editing, tsim symbology thiab labeling, muaj pes tsawg leeg maps luam thiab hauv internet ntawv, geoprocessing cuab yeej thiab Model Builder ArcGIS, SEXTANTE hauv gvSIG los yog NYOM hauv QGIS, thiab lwm yam.

Hauv hoob no koj yuav kawm, kauj ruam yog kauj ruam mus rau:

• Paub qhov interface ntawm ArcGIS, gvSIG thiab QGIS.
• Ua haujlwm nrog cov khaubncaws sab nraud thiab cov kev pabcuam.
• Kho kom raug cov ntaub ntawv qhia chaw.
• Ua hauj lwm nrog kev sib koom tes thiab georeferencing duab raster.
• Tsim kev cim thiab cim npe.
• Tsim daim ntawv qhia sau.
• Tsim geodatabases thiab topology.
• Ua qhov kev soj ntsuam pom.
• Ua haujlwm nrog SEXTANTE.
• Luam tawm cov ntawv hauv online.

Kawm hauv internet ntawm Spatial Databases: PostGIS. 

Pib kev tswj cov ntaub ntawv qhib qhov chaw xa ntawv PostGIS.

Hauv chav kawm no yuav tsum muaj xws li: Yuav ua li cas import shapefiles rau cov ntaub ntawv database? Yuav ua li cas kom ceev cov lus teb thaum khiav queries? Yuav ua li cas yog kev soj ntsuam spatial? Vim li cas ho muaj ib hom geometry thiab hom thaj chaw? Yuav ua li cas pom cov ntaub ntawv nyob hauv PostGIS?

 Tsis tas li, koj yuav kawm txujci, kauj ruam yog kauj ruam:

• Yuav ua li cas rau nruab PostgreSQL + PostGIS
• Yuav ua li cas los ua ib tug database thiab nruab nrog qhov chaw muaj peev xwm
• Chaw ua si cov ntaub ntawv qhia
• Yuav ua li cas saib thiab nkag mus rau hauv PostGIS
• Dab tsi ntawm hom geometry tshwm sim
• Ua li cas kuv ua qhov kev soj ntsuam thiab qhov kev khiav dej num muaj nyob hauv
• Yuav ua li cas kom ceev cov queries
• Yuav ua li cas ua hauj lwm nrog raster cov ntaub ntawv
• Yuav ua li cas ua hauj lwm nrog OpenStreetMap cov ntaub ntawv

ArcGIS kawm hauv chav kawm. 

Kawm yuav ua li cas thiaj li daws tau cov haujlwm thoob plaws thiab thaij duab GIS tus neeg hauv kev lag luam hauv ntiaj teb.

Qhov no yog ib tug ua kom tiav cov hoob kawm nyob rau hauv uas koj kawm ua hauj lwm nrog GIS raster thiab vector, editing, symbology thiab labeling, projections, georeferencing, geoprocessing, tsim geodatabases thiab topology, muaj pes tsawg leeg maps rau printing thiab publishing web viewers nrog ArcGIS hauv internet.

Hauv hoob no koj kawm, kauj ruam yog kauj ruam:

• Yuav ua li cas khiav lag luam nrog cov ntxhuav
• Ua haujlwm nrog Kev Koom Tes
• Yuav ua li cas georeference raster dluab
• Yuav ua li cas khiav cov cuab yeej ArcToolbox
• Yuav ua li cas los soj ntsuam nrog Modelbuilder
• Tsim cov Symbology thiab Labeling
• Yuav ua li cas raster analysis nrog Spatial Analyst
• Yuav ua li cas los tsim geodatabases
• Yuav ua li cas los tsim cov kev cai topological
• Yuav ua li cas luam tawm maps hauv internet nrog ArcGIS hauv internet

Kawm hauv internet ntawm QGIS.

 Kawm yuav ua li cas thiaj li tswj tau lub peev xwm tshaj plaws thiab xav tau qhib qhov desktop GIS software hauv txoj haujlwm ua lag luam thoob ntiaj teb.

Nws yog ib chav kawm tiav uas koj yuav kawm ua hauj lwm nrog cov ntawv xov xwm thiab vector raster, projections, ib tsab, cim thiab cim sau npe, qauv qhia ntawv rau kev luam ntawv, geoprocessing, GRASS, online tshaj tawm, thiab lwm yam.

Hauv hoob no koj kawm, kauj ruam yog kauj ruam:

• GIS yog dab tsi?
• QGIS interface. Taw qhia txog kev sib koom tes.
• Symbology thiab labeling.
• Tsim cov ncauj lus thiab kho cov rooj.
• Chaw ua haujlwm chaw.
• Kev sib sau ntawm GRASS rau hauv QGIS.
• Kev tsim cov cim rau cov ntawv luam tawm thiab hauv internet ntawv.
• Kev koom ua ke nrog spatial databases: PostGIS.

Cov kev kawm ua haujlwm nrog Virtual Chav Kawm, kom lawv tuaj yeem nqa tau txhua lub sijhawm thiab nrog kev nkag mus 24-teev. Thiab peb pom tias nws nthuav li cas lawv siv qhov zoo dua ntawm blog thiab lawv daim ntawv xa npe ua qhov ua yeeb yam rau qhov zoo ntawm lawv cov kev kawm.
