台北盆地
Xindian is located on the south side of the Taipei Basin, mainly on the plains between the Xindian Creek, its tributaries, and the mountains (the Xueshan Range). The Nanshi River merges with the Beishi River in Xindian, forming the Xindian Creek, one of the major tributaries of the Tamsui River. The Xindian Creek generally flows from south to north, dividing the city into east and west sides of the creek. Although the western side (Ankeng) covers a larger area, residential, administrative, commercial, and transportation centers are all on the eastern side of the creek at Dapinglin (大坪林). Population distribution in the Ankeng region is mainly concentrated in the southeastern hillside residential communities.
