Contour Clips
Questions & answers

Before you trust us with your basemap.

Straight answers on data, formats, accuracy, and what happens when something goes wrong. If yours isn't here, just ask.

01 — Data & accuracy

Which coordinate system and datum do I get?

Whatever you specify at order time. Washington State Plane zones in US survey feet are built in — EPSG:2926 (North), 2927 (South), and the NAD83 variants. Every package prints its horizontal and vertical datum on the summary sheet, so there's no guessing what you imported.

How current is the imagery and LiDAR?

It depends on the source, and we tell you exactly which one. NAIP refreshes every couple of years at roughly one-meter resolution; DNR LiDAR vintage varies by location. The source name and capture year are stamped on the summary sheet for every layer.

Is this survey-grade? Can I stamp it?

No — and we won't pretend otherwise. A clip is public source data, clipped to your boundary and reprojected. It's built for basemapping, design backdrops, feasibility, and constraints screening, not as a substitute for a field survey or a stamped boundary determination. It saves you the afternoon of gathering data; it doesn't replace your professional judgment.

02 — CAD & formats

Is it really CAD-ready, or just GIS files?

Really CAD-ready. Every vector layer ships as a DXF sibling alongside the shapefile, and you can add a LandXML existing-ground surface that drops straight into Civil 3D. Layers are named the way you'd name them by hand. DWG is available on request.

What software does it open in?

Civil 3D and AutoCAD via DXF/DWG and LandXML; QGIS and ArcGIS via shapefile and GeoTIFF. If it reads standard CAD or GIS formats, it can read our clip data.

What contour intervals can I choose?

You can choose any interval that you need, generated from DNR LiDAR. Pick the interval when you add the LiDAR layer.

03 — Ordering & delivery

How fast is "about 15 minutes"?

That's the typical turnaround for a standard job once payment clears - the package is built, quality-checked, and emailed to you automatically. A job flagged for review takes longer, but we will let you know.

What if a data source is down or a layer fails?

The order is held and a human checks it before anything ships. A package missing a layer you paid for never goes out the door, and you aren't billed for it.

How do I actually get the files?

A download link arrives by email when the job finishes. The link is good for seven days. The files are yours to keep once you've downloaded them.

04 — Licensing & coverage

Can I use a clip in my client deliverables?

Yes. We only ship data from sources licensed for redistribution - public city, county, state, and federal services.

05 — Billing

Is there sales tax?

Yes. Clips are a data product, so Washington retail sales tax is calculated and added at checkout based on the delivery location.

What's your refund policy?

If we can't build what you ordered, you aren't charged, or you're refunded if payment already went through. Because a clip is delivered data, we handle anything that's wrong with a completed package case by case. Send us an email us and we'll make it right.

Can you also digitize / analyze / do a custom layer?

For custom work, get in touch and we'll follow up with a quote.
