LCMAP to Lead Workshop at Pecora 21

Release Date:

The USGS Land Change Monitoring, Assessment, and Projection (LCMAP) team will lead a workshop at the joint meeting of the 21st William T. Pecora Memorial Remote Sensing Symposium (Pecora 21) and the 38th International Symposium on Remote Sensing of Environment (ISRSE-38).

Pecora 21

The workshop, titled “Demonstration and Application of the LCMAP Product Suite,” will take place from 9-11:30 a.m. on Oct. 6, 2019, the first day of the weeklong conference in Baltimore, MD.

LCMAP couples novel methodologies with every cloud-free Landsat observation since the 1980s to produce annual land cover and land change products and make them readily available to the research community.

The workshop announcement comes as the LCMAP team at the USGS Earth Resources Observation and Science (EROS) Center works to finalize the full release of its product suite for the conterminous U.S., built using Landsat Analysis Ready Data (ARD) and a modified version of the Continuous Change Detection and Classification (CCDC) algorithm developed by Zhu and Woodcock (2014). 

LCMAP products represent ten land cover and land change geospatial datasets, among them primary and secondary land cover classes with associated model confidence, annual land cover change, time of spectral change, change magnitude, and spectral stability period. 

Alongside annual and interannual change data from 1985-2017 and yearly product suite updates thereafter, the LCMAP team leads a host of monitoring, research and development, and land cover projections projects designed to advance the understanding of land change science.

The initiative’s goals align closely with the theme of October’s joint conference, “Earth Observation – Continuous Monitoring of Our Changing Planet: From Sensors to Decisions.” 

Sample data from the southern California released in spring 2019 will form the basis of the hands-on workshop. Participants must bring along a laptop with a minimum of 5 GB of storage, loaded with image viewing and processing software such as ERDAS, Imagine, ArcGIS, or QGIS.

It is recommended that participants download the sample data prior to the workshop. The session is limited to 30 participants.

An overview of LCMAP and progress in the continuous monitoring of U.S. land cover will be offered during the symposium, as well. Other LCMAP topics to be discussed in Baltimore include:

- Detailed LCMAP product descriptions,

- Quality control and assessment of LCMAP reference data,

- Use of reference data for accuracy assessment and area estimation,

- Initial LCMAP prototype land cover classification composition and change metrics from 1985-2016,

- Characterization of landscape thermal features using Landsat ARD and LCMAP products

- Comparations between LCMAP and National Land Cover Database (NLCD) maps

- LCMAP land cover projections,

- LCMAP Applications in hydrological sciences,

- Future directions and updated capabilities for LCMAP.

LCMAP Sample Products

The USGS LCMAP is the foundation for an integrated land change science framework. This new generation of land change and land cover data are provided to the science community as a suite of products. The products are developed from 30-m Landsat TM, ETM+, and OLI for the years 1985 to 2017. The provisional product suite includes five land cover products and five spectral change products.

LCMAP Captures ‘Stories of Change’ with New Datasets

If a new homeowner wants to know the history of their abode, there are places to turn.

County offices list ownership details and building permits, showing the dates of additions, fences and the like. If the house is old enough, local historical societies may even have archived photographs of the home’s exterior at various points in time.

EROS Workshop Offers First Look at Land Change Monitoring, Assessment, and Projection Products

The mapping and classification of land use and land cover has long been a primary duty for the U.S. Geological Survey (USGS), and remotely-sensed data at the Earth Resources Observation and Science (EROS) Center has served as the backbone of the Survey’s modern efforts.

In recent years, two advancements in remote sensing emerged that promise to revolutionize the field.
