Methods and systems for location determination and navigation using textual information may comprise capturing images of sources of textual information in the vicinity of a wireless communication device (WCD). Text may be extracted from the sources and a position of the WDC may be determined based on a comparison of the extracted text a stored database of textual information. An orientation of the text may be sensed and may be utilized with the extracted text and determined distances from the sources for the position determining. Locations of the sources and/or the captured images may be stored in the database. An instruction to capture images in a different orientation may be received when the positioning does not meet an accuracy requirement. A distance from the sources of textual information may be determined based on known optical properties of a camera in the WCD, such as focal length and/or and focus setting.
