<ul><li><b>Purpose and Use: </b>Designed to identify and display the closest fire station to specific hundred blocks within a city based on road miles. Used in the public- facing ISO Class Lookup application.</li><li><b>Data Source:</b> The creation of this dataset leveraged City of San Marcos's <a href='https://data-cosm.hub.arcgis.com/maps/e06beee5477a4f0495860535fdebac49/about' target='_blank' rel='nofollow ugc noopener noreferrer'>Centerline dataset</a> and existing fire station locations.

While efforts are made to ensure accuracy, there may be discrepancies due to changes in road conditions, unrecorded updates, or manual data entry errors. Users should consider these factors when interpreting the results and are encouraged to verify specific findings against current local conditions when precision is critical.</li><li><b>Related Items:</b> <a href='https://cosm.maps.arcgis.com/apps/instant/lookup/index.html?appid=79b47863984a4952aaa49f472e9195c7' target='_blank' rel='nofollow ugc noopener noreferrer'>ISO Class Lookup<br /></a></li></ul>
