How to Use This Union, Louisiana Map

This interactive map shows the street layout and satellite imagery for Union, Louisiana. Use the Map and Satellite buttons above to switch between street map and aerial imagery views. Use the + and − buttons to zoom in or out, or scroll your mouse wheel while holding the Control key to zoom. On a touchscreen, use a two-finger pinch gesture. Drag the map to pan to any area of Louisiana or beyond.

Click ⛶ Fullscreen to expand the map to fill your screen. To return to the normal page view, press the Escape key, click the ✕ Exit Fullscreen button that appears above the map, or on a mobile device tap the back button (Android) or the close icon (iOS).

TOPO MAPS — NEW. Click the green 🔍 Search Maps button below the map to open a second map with a Base map row offering three choices. OSM is the standard OpenStreetMap street map. Topo shows the official USGS topographic maps from The National Map — contours, hydrography, land cover and shaded relief, the same mapping used for hiking, hunting and back-country navigation in the Adirondacks, the Catskills and the Finger Lakes. Imagery shows USGS aerial photography, mostly 1-metre NAIP. The search box finds any US town, county or landmark by name, so you are not limited to Union.

Reading the map like a paper quad. Click Grid to overlay the U.S. National Grid (USNG), labelled along the edges exactly as a printed topographic sheet is — at normal zoom the squares are one kilometre across, so you can read a six-figure grid reference by eye and judge distance directly off the map. Click Measure, then tap two points, to get the distance between them together with the grid bearing in degrees and mils, the true bearing, and the magnetic bearing to set on a compass.

Click 📍 My position to take a single GPS reading from your device. It marks where you are and reports your position as a USNG grid reference as well as plain latitude and longitude — USNG being the format FEMA and US search and rescue teams work from — with a Copy position button so you can paste it straight into a text message. It takes one reading and stops, rather than tracking continuously, to conserve your battery. Note that map tiles need cell coverage, but a GPS reading does not — your coordinates stay correct even where the map itself cannot load.

Union asserts its presence upon the flat, alluvial plains where the Mississippi River carves a slow, deliberate path through the heavy soil. It lies 10.5 miles south of Gonzales, LA (from Gonzales, LA: bearing 175°T), and is situated 5.4 miles east of Donaldsonville. The landscape surrounding Union remains defined by the weight of this water, which carries the silt of a continent past the banks in a perpetual, muted churn. To the west, the earth dips toward the Nita Crevasse, a remnant of the land’s volatile shifting, while the horizon remains unbroken by any significant rise, save for the distant, singular silhouette of Indian Mound. The air here holds a permanent, humid stillness, often thick with the scent of damp earth and the deep, green respiration of the surrounding vegetation that thrives in the absence of any true mountain shade.

Sugar cane dominates the fields that stretch away from the river, creating a vibrant, emerald geometry that marks the seasons in Union through cycles of planting and harvest. This agricultural pulse has long dictated the rhythm of local life, drawing upon a history of labor and land management that persists in the quiet, industrial hum of modern operations. Residents find leisure in the simple green expanse of Lemannville Park, a small sanctuary of grass and shade only a short distance away, while those seeking the stillness of open water look toward the distant, calm surface of Lake Verret. Life in Union moves with a heavy, deliberate gravity, reflecting a culture shaped by the constant, unseen pressure of the river’s current and the slow, relentless expansion of the growing fields.
