With the rise of the digital age, geographic data is more central than ever to corporate strategy. Oktri’s mission? To help you master this critical information, from field acquisition to the resulting business decisions. We provide the geospatial consulting and expertise needed to support organizations for whom the geographic dimension is key to success.
Areas of work
Six ways of working together, from strategic scoping to operations supervision.
Define what your organization needs to collect or to provide regarding its geographic dimension.
A poorly chosen coordinate system comes at the cost of metric discrepancies, ten years later.
Specify, contract, and supervise surveying operations, both onshore and offshore.
Select the observation data that answers the question at hand, rather than simply the data with the highest resolution.
Make technical data accessible, understandable and reusable by people who did not produce it.
Reality Capture offers a paradigm shift to those who master the entire workflow, from acquisition to the utilization of 3D data.
I personally lead consulting engagements to ensure you receive tailored support. When projects require it, I draw upon a network of highly specialized experts (geodesy, hydrography, remote sensing, GIS) with full transparency, so you always know exactly who is working on the project.
Based in Central America, in a time zone midway between California and Europe, I collaborate remotely with an international clientele while remaining available for on-site work whenever operations demand it.
Engagement formats
The principle is that of the octree: detail only goes down where it changes the answer. Every format has a duration, a deliverable and a price known before the work starts.
The whole volumeOne hour to look at the situation as a whole and decide whether to go further.
A first subdivisionA diagnostic of a few days that cuts the subject up and says where the stake lies.
Detail, where it is usefulAn engagement, an operations watch or longer-term support, only in the octant that asks for it.
One hour, by video call, at no charge.
You describe your situation, however briefly. Together we work out whether support makes sense, and which kind. If the answer fits in an hour, it is given during that hour.
It is the way into everything else, and neither side is committed to anything.
Two to three days, remotely, within two weeks.
Reading the existing documents, interviews with the people who produce, manage or use the data, then a decision note: what is really at stake, the options, the recommendation and what it costs.
The note is presented in session. It is written to be read by a management team with no time to read everything again, and to stand without me. If an engagement follows, the diagnostic is deducted from it.
From two to twelve weeks, at a fixed price.
An engagement has a written scope, a price set before it starts, dated checkpoints and a deliverable your teams can pick up without me. Four kinds come up most often.
By the day, on site or on board.
Representing your interests during a survey operation, on land or at sea: reviewing the procedure before mobilisation, daily checks on data quality, decisions on the spot when the unexpected happens, and an end-of-operation report.
The contractor knows the job. My role is to check that what is delivered is what you bought, while it can still be corrected.
Three to eight days a month, over six months.
An outsourced geospatial lead, for organisations too small to recruit one or going through a period when they would need two. Arbitration, specification reviews, contractor relations, and bringing the existing team up to speed.
The days are planned each month; unused days are not carried over. It is the format in which governance flaws show up, and get fixed, fastest.
When a subject goes beyond my own scope (detailed hydrography, image processing, GIS development), I bring in a specialist whose work I have seen. They are named in the proposal and billed at cost, plus coordination.
Amounts are before tax, in euros or in dollars depending on your region. They cover preparation, presentations and the exchanges between working days. They do not cover travel, billed at cost, nor licences or data to be bought on your behalf.
Every proposal is priced on a written scope, and the price is known before the work starts.
Let’s take an hour to discuss your challenges and determine together whether guidance would be appropriate.
Did you know?
Say it “ok-tree”. It is the name of a data structure made to file away space: the octree, short for octal tree.
The idea fits in one sentence. Take a cube holding the whole scene and cut it in half along all three directions: you get eight equal cubes, the octants. Do it again inside each of them, but only where something is left to describe. Empty space stops at once, dense space keeps dividing.
What comes out is not a regular grid, it is an index: where a point sits in the tree is where it sits in space. Asking what fills a volume no longer means reading everything, only following the branches that cross it and ignoring the rest. That is how a point cloud of several billion returns opens in a browser, or how a pipeline is checked against every obstacle around it in milliseconds.
An octree does not look everywhere with the same care: it puts detail where detail changes the answer, and leaves the rest coarse. Which happens to be a way of handling a problem, too.
