# FAQs

<details>

<summary>How does Spexi approach privacy compliance?</summary>

**Privacy Safeguards:**\
Spexi’s imagery is captured from an altitude that prevents the identification of individual faces and personal details. This approach ensures that no personally identifiable information (PII) is captured.

\
**Regulatory Adherence:**\
Spexi complies with all applicable privacy laws and follows industry best practices. For region-specific privacy concerns, users are encouraged to review local guidelines or consult with legal experts.

<summary>What quality control procedures exist to ensure high quality data?</summary>

* **Optimal Lighting:** Images are captured under lighting conditions that minimize shadows and distortions.
* **Flight Regulation Compliance:** Flight times are carefully restricted to meet drone regulations, ensuring clear and high-resolution images.
* **Demand-Based Updates:** Areas of high demand are prioritized for frequent updates rather than indiscriminate coverage.
* **Upcoming Features:** A side-by-side comparison feature is in development to allow users to compare images across different timeframes easily.

<summary>How accurate is your imagery?</summary>

* **Ground Sample Distance (GSD):**
  * Spexi imagery offers a GSD of approximately 2.8 centimeters per meter at nadir (directly beneath the drone).
  * This metric implies that for every 1 meter on the ground, the potential positioning error is 2.8 centimeters.
* **Overall Accuracy:**
  * Typical imagery accuracy falls within a 5–10 centimeter range.
  * These values make Spexi’s imagery comparable to high-resolution satellite imagery for most mapping and analysis applications.

<summary>Do you support ortho imagery?</summary>

Currently, Spexi primarily supports oblique imagery due to its operational efficiency and cost-effectiveness.

* **Ortho Imagery Considerations:**
  * Ortho images require additional flight time and processing.
  * These factors increase overall operational costs.
  * Spexi is evaluating the possibility of introducing ortho imagery support in the future, and updates will be provided as developments occur.
