  • Flexible workflows — Annotation processes adapted to your categories, guidelines, tools, and specifications
  • Quality-driven delivery — Defined review and validation processes to maintain annotation consistency
  • Scalable capacity — Support for both pilot datasets and ongoing high-volume annotation requirements
  • Complex visual data — Capability to work with detailed aerial, property, geospatial, engineering, and infrastructure imagery
  • Reliable delivery — Structured project management with defined workflows, timelines, and deliverables

What DIN Needs from You to Start

To begin your data annotation project efficiently, we require the following information:

  • Source Data
    Images, videos, aerial imagery, point clouds, GIS datasets, documents, or other relevant data to be annotated.
  • Annotation Requirements
    Objects, features, categories, attributes, and specific elements that need to be identified or labeled.
  • Annotation Guidelines
    Existing labeling instructions, class definitions, examples, edge cases, and project-specific annotation rules.
  • Quality Requirements
    Required accuracy levels, validation criteria, review processes, and quality expectations.
  • Output Requirements
    Preferred annotation format, file structure, naming conventions, metadata, and delivery requirements.
  • Project Volume & Timeline
    Approximate dataset size, expected annotation volume, project milestones, and required turnaround time.

Once the required information is received, our team reviews the dataset and annotation requirements, establishes the appropriate workflow, and proceeds with annotation and quality validation according to the agreed specifications.

Tool-Agnostic Expertise. Your Platform, Our Precision.

Whether you use a preferred annotation platform, internal labeling environment, GIS workflow, or custom AI pipeline, DIN can adapt its annotation process to your existing ecosystem. We align with your tools, annotation guidelines, data structures, and delivery requirements-helping you integrate annotated datasets into your workflow without unnecessary changes.

Frequently Asked Questions (FAQ)

Annotated data can be delivered in formats and structures aligned with the project requirements, including commonly used image, text, JSON, CSV, GIS, and other client-specified formats. Final formats can be agreed during project planning.

Yes. Annotation categories, class definitions, labeling rules, attributes, edge cases, and quality requirements can be defined according to your project specifications and dataset requirements.

Yes. DIN can annotate video datasets frame by frame and track objects across sequences. This can support applications involving object detection, movement tracking, activity recognition, and scene understanding.

Yes. We can create customized annotations for solar, roofing, and property datasets, including roof areas, solar panels, trees, obstructions, buildings, driveways, pathways, swimming pools, fences, and other relevant property features.

Yes. DIN can annotate aerial and satellite imagery to identify and classify features such as buildings, roofs, solar panels, roads, trees, pathways, vehicles, fences, property boundaries, and other geographic or infrastructure elements.

We can work with a wide range of visual datasets, including aerial imagery, satellite images, property photographs, roofing images, solar imagery, infrastructure images, road scenes, and other project-specific visual datasets.

DIN provides image, video, 3D, point cloud, and geospatial data annotation services. Our solutions include object detection, classification, segmentation, polygon, polyline, keypoint, and object-tracking annotation based on project requirements.
