Jeff Zivkovic, owner of Third Rock Analytics.

Hi, I'm Jeff.

I run Third Rock Analytics. My background is in Electrical and Computer Engineering (Ohio State) and Geoinformatics (MS, UT San Antonio), with several years of GIS work across academia, energy, and engineering.

I like the whole chain: raw data, processing, analysis, and a map that makes the answer obvious. When you hire Third Rock, I'm the one doing the work.

  • Direct. No account managers or handoffs. You talk to the analyst.
  • Budget-aware. Pricing and scope built around nonprofit and small-organization budgets.
  • Local. Based in Washington State and available for site visits and in-person presentations.

Common questions

Anything else, just ask on the call.

What does a project cost?

It depends on the scope. After the free call you get a written scope with either a fixed price or an hour estimate, so you know the cost before any work starts. Nonprofit and grant-funded projects get a reduced rate.

Do you work with private landowners?

Yes. Alongside nonprofits and agencies, I work with farms, vineyards, ranches, and other private land managers.

Do you only work in Washington?

No. Most of the work is done remotely, so location isn't a limit. If you're in Washington, site visits and in-person presentations are also an option.

What data do I need to have?

Possibly none. Free public sources like satellite imagery, aerial photos, and elevation data cover a lot of questions. If you do have field data, spreadsheets, or GIS files, bring them and we'll put them to use.

How long does a project take?

It depends on the scope, and your written scope includes a timeline. If you have a hard deadline, mention it on the call. Rush timelines are possible.

What if I'm not sure what I need?

That's what the free call is for. Describe the question you're trying to answer, and I'll suggest what would actually help, even if it's not a project with me.
