When land near Waskom catches your eye, the Longview GIS map lays out parcel boundaries plus basic tax data. This Longview guide covers: which viewer to open, the fastest ways to search, and the limits worth knowing.
Opening the Longview GIS map
Parcel maps here are usually run by the county, not the town, and for Longview that means the Texas county CAD map.
Pulling up a parcel
Begin with the Texas county CAD map; it maps each assessed parcel around Uncertain and Scottsville. Near Uncertain, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. With a lot near Hallsville, the parcel card normally shows the owner of record, assessed acreage, the parcel number and sometimes recent sales.
Where Longview fits in
Longview sits in Harrison County, Texas, so its parcels are on the county's map. For a parcel near Waskom, the municipality handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Acreage past the city limits out by Hallsville usually falls under county rules, not municipal ones.
Finding the right lot
Acreage around Hallsville might not have a street number, which means panning to it and clicking. If you're looking near Scottsville, searching by parcel number never misses, and it's printed on tax bills.
What the layers show
For acreage around Hallsville, layer lists often include zoning, flood zones, city limits, school districts or contours; not every viewer has them all.

Harrison County meets Caddo Parish, LA, Gregg County, Marion County, Panola County, and Rusk County, and each of those keeps its own parcel map.

Using it on a phone

How land is described here
Tracts outside towns near Uncertain are often described by metes and bounds, listing bearings, distances and landmarks. Platted lots around Scottsville are typically described by lot and block, which is simpler to follow. Keep the legal description for land near Scottsville before you request a deed or survey.
Backing up the map with records
The map is an index, not the title: deeds, plats and easements covering ground around Scottsville are kept by the County Clerk. In and around Waskom, have ready the instrument number listed on the parcel record and the lookup takes minutes.
Getting answers from the right desk
For assessment questions about property around Uncertain belong with the appraisal district, since that office keeps the assessment data. Building or septic questions for a lot near Uncertain go to planning, building or health offices, town or county, depending on location.
Browser tips
If the viewer stalls on a phone near Marshall, switch browsers or turn off pop-up blockers; the Platbookmapper county page tracks the current link.
