This page serves as a GIS hub for maps created by the Bureau of Statistics and Plans for planning, permitting, location and point administration e.g. property, address, road etc, hazard mitigation, disaster and emergency response, and conservation. These maps were developed using layers and data developed by the GovGuam network agencies, and by the federal government. The development of these maps, map meta data, and sourcing is ongoing. Most map layer sources can be found in the layer details in ArcGIS online. A detailed listing of layer source information will be available by early September 2025. 

For questions or issues accessing these maps contact Matthew Santos at matthew.santos@bsp.guam.gov. BSP cannot and will not provide layers or data related to utilities or cad files used for internal property updates. This would violate the NDA’s and terms that  BSP is subject to. 

The publicly available parcel inventory is for informational and planning purposes only. Therefore, any parcels provided is not intended to be used for, conveyance, authoritative definition of legal boundary, or property title. The mapping is on-going and as new information is available, it will be added to the inventory.
