Methods for Collectinng POI data and Street View data

Collect POI Using Baidu API

I use Baidu Place API to do this. http://lbsyun.baidu.com/index.php?title=webapi/guide/webservice-placeapi

Usage

Modify the parameter in the main function in the bottom of the code.

  • Set the query key word. I recommend to follow the categories of Baidu. http://lbsyun.baidu.com/index.php?title=lbscloud/poitags
  • Set the boundary of the region. The region should be a rectangle region followed by minLat,minLon,maxLat,maxLon. For example: region="39.915,116.405,39.975,116.415"
  • Change the length of square's side, the smaller the more accuracy while slower. For example: location = LocationDivide(region, 0.01)

Collect Street View Using Baidu API

I use an arctoolbox: CreatePointsLines.tbx to do this.

Usage

  • Import network / road polyline data in ArcGIS.
  • Use CreatePointsLines toolbox to generate points along with the polylines with equal distance.
  • Compute points' coordinates and then export them into a csv file.
  • Set the csv file path to download the pictures.
