Geospatial Data

The following information provides Forest Service data for the majority of the 4FRI area, including GIS, stand data, LiDar, and general project maps. This data is not all-inclusive, nor is this the only way to characterize the resources. Additional data will be posted as it becomes available.

LiDAR

Lidar Acquisition Map 09-12-2019LiDAR data is available from three separate acquisitions flown in 2013, 2014, and 2018. The two acquisitions in 2013 and 2014 covered areas in the southeastern portion of the Coconino, northern portions of the Tonto, and portions of the Apache-Sitgreaves extending from the Black Mesa Ranger District to the Alpine Ranger District. The acquisition in 2018 covered the Williams and Tusayan Ranger Districts on the Kaibab as well as portions of the Flagstaff Ranger District on the Coconino (acquisitions map).

LiDAR data will be available in the future over an area covering the remainder of the ponderosa pine belt on portions of the Flagstaff and Mogollon Rim Ranger Districts on the Coconino (acquisitions map). This data is not expected to be available until the spring/summer of 2020.

If you would like to make arrangements to obtain copies of the currently available Lidar data, please send a request to 4FRI_Comments@fs.fed.us or by using our Contact Form and include “LiDAR” in the subject line. You will need to supply an external hard drive capable of storing multiple terabytes of data, depending on your area of interest. Additionally, you will be required to sign a non-disclosure agreement intended to protect the locations of sensitive sites.
